- The Unable to access the JAR file is a standard error when you don’t have compatible software to open it.
- Some users reported that using stable file openers fixed the issue for them.
- You can also fix this issue by uninstalling and downloading the latest version of Java.
Java browser plug-ins might have gone out of fashion, but many programs run off Java. For example, you can open Java programs with JarFiles, among other software for opening JAR files.
However, some Java software users can’t always open JAR programs with the Unable to access JarFile error message popping up. This guide will show you some practical ways to get past this error message.
Why does it say unable to access jar?
The inability to access JarFile on Minecraft or Forge can be caused by mistakes on your path or issues with the software. Below are some of the prevalent causes:
- Outdated Java version: If your Java version is obsolete, you cannot access JarFile using the docker container. You need to update Java to the latest version.
- Wrong default program: Sometimes, this issue might be because you have not set the default program to open the JarFiles. Choosing Java as the default app for opening JAR files should fix this.
- Issues with the JAR file path: If the path to your jar file is incorrect, you can get this error. The solution here is to ensure the path is correct.
How can I fix the unable to access JarFile error?
Before proceeding to the fixes in this guide, try the preliminary troubleshooting steps below:
- Add .jar extension to the JAR file name
- Beware of spaces in the JAR file path
- Add quotes to the JAR file path if it contains space
- Move the JAR file to another folder
- Use a file opener software
If the fixes above fail to solve the issue, you can now move to the fixes below:
1. Update your Java version
- Press the Windows key + R, type appwiz.cpl, and click OK.
- Right-click the Java app and select the Uninstall option.
- Now, go to the official website to download the latest version of the Java app.
A broken or outdated app can cause the unable to access the JarFile issue. Downloading the latest version of the app should fix the problem.
2. Select Java as the default program for JarFiles
- Open File Explorer and the folder that includes your JAR file.
- Right-click the file and select Open with, and then Choose another app.
- Select Java if it’s listed among the default programs.
- If Java isn’t listed among the programs, select the Look for another app on this PC option.
- Then browse to the Java bin folder, select Java and press the Open button.
JAR file error messages usually pop up when Java isn’t configured as the default software for a JAR file. This can be the cause of the unable to access JarFile.
Setting Java as the default program should fix the issue here.

Исправлено: Невозможно получить доступ к Jarfile —
Не удалось открыть jarfile
Что вызывает ошибку «Невозможно получить доступ к Jarfile»?
Прежде чем переходить к решениям, убедитесь, что у вас есть активное подключение к Интернету и привилегии учетной записи администратора.
Решение 1. Установка последнего обновления Java
Как упоминалось ранее, для программ, запускающих файлы JAR, на вашем компьютере должна быть установлена правильная архитектура, т. Е. Java. Кроме того, это должна быть последняя версия, выпущенная для пользователей. Если у вас не установлена Java, вы можете напрямую загрузить и установить ее. Если у вас более старая версия, мы сначала удалим ее, а затем установим последнюю с официального сайта.
Удаление старого Java — менеджера приложений
Решение 2. Настройка файловой ассоциации по умолчанию
Также может появиться сообщение об ошибке: Java не установлен в качестве обработчика по умолчанию для файлов JAR на вашем компьютере. Программа архивации может быть выбрана в качестве средства открытия JAR-файлов по умолчанию, что может не дать ожидаемого результата. Мы можем попробовать изменить сопоставление файлов и проверить, устраняет ли это проблему.
Открытие JAR-файлов с помощью Java
Нажмите Windows + I, чтобы запустить настройки. Теперь перейдите к Программы и выберите Приложения по умолчанию с левой панели навигации.
Изменение файловой ассоциации по умолчанию
Решение 3. Проверка на наличие вредоносных программ
Если вы по-прежнему получаете сообщение об ошибке при запуске операционной системы или любой другой программы, вам следует проверить, нет ли на вашем компьютере вирусов или вредоносных программ. Эти объекты используют ваш реестр и после изменения нескольких ключей делают JAR-файл непригодным для использования.
Сканирование с использованием вредоносных байтов
Вы должны выполнить тщательную проверку на своем компьютере, а затем выполнить Решение 1, чтобы убедиться, что все записи и ассоциации файлов удалены, а затем переделаны при переустановке Java. Вы проверяете нашу статью о том, как удалить вредоносное ПО, используя Malwarebytes.
Решение 4. Проверка документации (для разработчиков)
Разработчики также испытывают это сообщение об ошибке, когда они пытаются запустить файлы JAR, когда они кодируют с Java или другим языком. Это может быть очень хлопотно и, вероятно, остановит вашу задачу под рукой.
Ошибка кодирования Java
Для диагностики и устранения ошибки рекомендуется прочитайте документацию по функции или утилиту, которую вы используете для открытия или запуска файлов JAR. Возможно, вы неправильно указали путь к файлу или, возможно, передали неверные параметры в функцию. Вы можете легко получить демонстрации функций, которые вы пытаетесь реализовать на популярных веб-сайтах по кодированию, таких как Stack Overflow. Определите свою ошибку и исправьте ее, прежде чем снова запустить программу / функцию.

Fix Java Virtual Machine Launcher Error on Windows 11/10
A programming language like Java is more than just a way to write programs; game and app developers use it too. However, it’s very common to experience Java crashes. If you are having trouble when trying to launch an application that is built around Java then this guide will help you fix the problem.
Not all Java virtual machine errors are the same. They can occur for many different reasons. In this article, we will explain what the most common causes of Java virtual machine launcher error and how to fix them.
What is Java in simple words?
Java is a popular programming language that can run on a variety of different operating systems and devices. It has many different uses, including in web development, mobile applications, desktop applications, and server-side programming. Java generates a virtual machine (VM) that executes the code written in Java. A Java virtual machine launcher error can occur if something goes wrong with the data or code that’s being processed by the Java virtual machine.
What is a Java virtual machine error?
A Java virtual machine error, also known as a JVM error, is classified as an error generated by the Java Virtual Machine. When this type of error occurs, it usually means that the computer cannot read or understand the code. This can happen for a number of reasons such as when the computer isn’t updated with required patches or if it’s not compatible with Java. If you come across a JVM error while using your computer, it’s important to know how to recover from this problem. Here, are some steps to take in order to fix this issue and continue using your computer.
How to fix Java Virtual Machine Launcher Error
Now let’s take a closer look at them:
1] Add a new system variable for Java
To fix this error, you must add a new variable to Java’s system and see if it solves the error. Please follow the steps below to resolve this issue:
Below you can find a detailed explanation of the above steps:
To get it started, open the System Properties window first. This can either be done through the Run dialog box or the File Explorer.
So, press the Windows + R keyboard shortcut to launch the Run command. Then type sysdm.cpl in the search box and click the OK button.
Alternatively, open the File Explorer using Windows + E keyboard shortcut. Then right-click on This PC and select the Properties option from the context menu.

If you have recently tried to open a JAR package file, only to receive the error, “unable to access Jarfile,” this simply means that your computer either doesn’t have the right software to open the file, or you have the wrong file path. Other common reasons for getting this error is if you have an outdated version of Java, your computer is infected with malware, or the default program for opening your JAR files isn’t set correctly. Before we jump into the solutions for this, let’s take a look at what JAR is.
Understanding JAR Package Files
Java Archive or JAR is a package file format based on ZIP architecture. It is used to group together multiple Java class files, their metadata, and any resources these files need to run into one single package. The purpose of doing this is to then distribute the grouped files as needed for the running of applications and programs. In order to run the executable file in a JAR package, you must have the latest Java Run-Time Environment installed.
If you are getting the error, “unable to access Jarfile” it means that you are encountering one of the following problems:
- Your system has malware that is either preventing the Jarfile package to open.
- The Jarfile package is corrupted from malware.
- You do not have the latest Java Run-Time Environment installed.
- The default program for accessing JAR files isn’t set.
- The file path for the executable Jarfile package is incorrect.
The “unable to access Jarfile” error is quite a common one since there are many popular programs that use Java as their programming language. For instance, Netflix uses it along with Python for applications in its back-end, while Spotify uses it to stabilize data transfer, and Minecraft uses it for its launcher. Other popular programs and services that use Java include: Uber, Amazon, LinkedIn, Google, and Android OS.
1. Update Your Java to the Latest Version
The most likely reason that you are getting the, “unable to access Jarfile” error is due to an outdated version of Java. Unfortunately, outdated versions of Java Run-Time Environment are prone to security risks and loopholes, so keeping it updated is highly recommended regardless of whether you are getting the above error.
- In your computer’s search menu, type in “Control Panel”.
- In the control panel window, choose “uninstall a program” under programs.
- In the list of programs, scroll until you see Java. Or use the search program box in the top right-hand corner of the window.
- Take a look at the version number and see if it matches the latest release.
- If it doesn’t, uninstall the program by right-clicking on it.
- Choose “yes” when prompted.
- From the official Java website, download the latest version.
- Once downloaded, use the setup wizard to install Java.
Now, re-try opening your JAR package to see if the problem is fixed.
2. Make Java the Default Program for Opening JAR Packages
If you are still getting the “unable to access Jarfile” error after updating your Java Run-Time Environment to the latest version, then you may not have Java set as the default program to use for opening JAR packages.
- In your computer’s taskbar, open File Explorer.
- Find the folder that contains your JAR package.
- Right-click on the folder and choose “open,” and then Java.
- If Java is not listed, select “choose another app”.
- In the window that pops up, choose Java from the list. If it is not there, choose the “look for another app on this PC” option.
- Browse your computer for Java and find the program. Select it and hit the “open” option.
- A prompt window may open. If it does, choose “okay” and “open”.
- Double-click on your JAR package executable to open.
When browsing for Java on your computer in step 6, the most common place for it to be is in Program Files (x86)/Java/Java <Version>/Bin/Java.exe. Keep in mind that Java is usually installed to the default hard drive disk where your operating system is, unless you do a custom installation path. So, keep this in mind when trying to find Java on your computer.
3. Set Java as a Default Association Permanently
If you use a lot of programs or applications that use the Java Run-Time Environment, it is recommended that you set Java as a default association permanently in your computer, so that any JAR packages or files are automatically opened by Java.
- Press the Windows key and “I” on your keyboard to open Settings. Alternatively, type “settings” into your computer’s search menu.
- Click into the “apps” option in the Settings window.
- Choose “default apps” in the left-hand sidebar.
- Scroll until you see, “choose default apps by file type” and click it.
- Now, look for .jar in the list and click on “Choose a default” next to it.
- Find the Java Platform Program (Java Run-Time Environment) on your computer.
- Save the changes and exit.
Now restart your computer for the changes to take effect and see if you can open your JAR package without the, “unable to access Jarfile” error.
4. Check for Malware to Eliminate Infections Causing Trouble
If you are still getting the “unable to access Jarfile” error, it may be from malicious malware. A virus can easily exploit your registry and modify it to make JAR packages unusable. It is highly recommended that you run a thorough scan of your entire computer to look for malware. If you find some, remove it and uninstall Java. Repeat fix 1 in this list to reinstall.
5. Configure Hidden Files/Folders/Drives to Show
While not as common, sometimes hidden files, folders, and drives can cause the “unable to access Jarfile” error.
- In your computer’s taskbar, open File Explorer.
- At the top of the window, click on the “View tab”.
- Now click on the “Options” button to the far right.
- In the new window that opens, click on the “View tab” again.
- In the list, choose the “Show hidden files, folders, and drives” option.
- Hit Apply and then hit OK.
6. Repair Your Java Programs with Jarfix.
If you are using programs that launch with Java and they are not responding to you, no matter how many times you try to open the application, then it may be time to repair your JAR associations. To do this, simply download Jarfix, a lightweight program that fixes hijacked JAR associations, and run it.
7. Check the Documentation If You Are a Developer
If you are working in Java as a developer and come across the “unable to access Jarfile” error, it is likely that there is a minor mistake within the coding. It is recommended that you go back through and re-read to make sure that you have the right file path and the correct parameters for the code to work. Depending on what utility you are using to open and run your JAR packages, you may need to go back through and re-read the documentation on how to get it functioning properly.
Wrapping It Up
In most cases, the “unable to access Jarfile ” error will be solved by updating your Java Run-Time Environment to the latest version, but if it doesn’t solve the problem, please do try out the other methods on this list. Let us know in the comments below if we were able to help you!

Я новичок, когда дело доходит до использования Java в Linux. Я клонировал репозиторий, в котором я заинтересован, и я не могу запустить код с моей машины. Команда, которую я пытаюсь сделать:
Ошибка, которую я получаю:
Сначала я подумал, что это была правка, поэтому я попытался запустить команду с sudo (получил ту же ошибку), я также видел один пример с файловым путем в кавычках, поэтому я пробовал это, но у меня также была такая же ошибка.
Я просмотрел файлы проекта, и на самом деле это не файл с именем example.jar. Есть ли команда, которую я должен запустить сначала, чтобы ее создать?
Заранее благодарим за помощь!

Да, чтобы запустить банку, она должна существовать.
При его создании вам необходимо сопоставить структуру каталогов с структурой пакета.
Например, ваши каталоги могут быть:
для источников и для файлов классов:
(часто вы найдете классы в ../bin/ .. вместо ../classes/ .. именованная папка или исходные файлы и файлы классов смешиваются в тех же каталогах)
соответствует структуре пакета:

I had encountered this issue when I had run my Jar file as
java -jar TestJar
java -jar TestJar.jar
Missing the extension .jar also causes this issue.
Fixed
I just placed it in a different folder and it worked.

Beware of spaces in the path, even when your jar is in the current working directory. For example, for me this was failing:

I had this issue under CygWin in Windows. I have read elsewhere that Java does not understand the CygWin paths ( /cygdrive/c/some/dir instead of C:somedir ) — so I used a relative path instead: ../../some/dir/sbt-launch.jar .
Just came across the same problem trying to make a bad USB.
I tried to run this command in admin cmd
But got this error:
Solution
1st step
Right click the jarfile in question. Click properties. Click the unblock tab in bottom right corner. The file was blocked, because it was downloaded and not created on my PC.
2nd step
In the cmd I changed the directory to where the jar file is located.
Then I typed dir and saw the file was named duckencode.jar.jar
So in cmd I changed the original command to reference the file with .jar.jar
That command executed without error messages and the inject.bin I was trying to create was now located in the directory.
Hope this helps.
i had the same issue when trying to launch the jar file. the path contained a space, so i had to place quotes around. instead of:

I had similar problem and i even tried running my CMD with administrator rights, but it did not solved the problem.
The basic thing is that make sure to change the Directory in cmd to current directory where your jar file is.
Do following steps:

to check this you can view extended attributes on the file
You can then clear the attributes with
For me it happens if you use native Polish chars in foldername that is in the PATH. So maybe using untypical chars was the reason of the problem.
My particular issue was caused because I was working with directories that involved symbolic links (shortcuts). Consequently, trying java -jar ../../myJar.jar didn’t work because I wasn’t where I thought I was.
Disregarding relative file paths fixed it right up.
In my case the suggested file name to be used was jarFile*.jar in the command line. The file in the folder was jarFile-1.2.3.jar . So I renamed the file to jarFile . Then I used jarFile.jar instead of jarFile*.jar and then the problem got resolved
It can happen on a windows machine when you have spaces in the names of the folder. The solution would be to enter the path between » «. For example:
To avoid any permission issues, try to run it as administrator. This worked for me on Win10.
I know this thread is years ago and issue was fixed too. But I hope this would helps someone else in future since I’ve encountered some similar issues while I tried to install Oracle WebLogic 12c and Oracle OFR in which its installer is in .jar format. For mine case, it was either didn’t wrap the JDK directory in quotes or simply typo.
Run Command Prompt as administrator and execute the command in this format. Double check the sentence if there is typo.

If it shows something like JRE 1.xxx is not a valid JDK Java Home , make sure the System variables for JAVA_HOME in Environment Variables is pointing to the correct JDK directory. JDK 1.8 or above is recommended (2018).

None of the provided answers worked for me on macOS 11 Big Sur. The problem turned out to be that programs require special permission to access the Desktop, Documents, and Downloads folders, and Java breaks both the exception for directly opened files and the permission request popup.
Fixes:
- Move the .jar into a folder that isn’t (and isn’t under) Documents, Desktop, or Downloads.
- Manually grant the permission. Go to System Preferences → Security and Privacy → Privacy → Files and Folders → java, and check the appropriate folders.

Unable to access jarfile is a common error in the latest version of Java programming language. In this article, the reader will be told about all the reasons behind this error and how they can use various procedures to remove this error. Let’s start with the causes of this error and then gradually move to all possible solutions of this error!

Why Does the Unable to Access Jarfile Error Message Arises?
The unable to access jarfile error message arises because the Java Virtual Machine (JVM) is unable to access or read a jar file specified in a command-line script or application. This error may be caused by issues such as incorrect file paths, corrupted jar files, or problems with command-line syntax.
Some other reasons are explained and listed below:
- Typo in the file name.
- Permissions issue.
- Missing dependencies.
– Incorrect Path
The incorrect path error message can occur when the path to the JAR file is not specified correctly. When a Java application is executed from the command line, the operating system needs to know the exact location of the JAR file to run the application correctly.
The path is a series of directories that lead to the location of the JAR file. An incorrect path to the JAR file can result in the unable to access jarfile error message.
– Typo in the File Name/ Syntax Errors
Another reason why this error message can occur is when there is a mistake in the spelling of the JAR file name or any other type of syntax error. The operating system uses the filename to locate and execute the JAR file, so any errors in the filename can result in the unable to access jarfile error message.
It is essential to double-check the spelling of the JAR file name, including the case of the letters. For example, if the JAR file is named “myJarFile.jar,” but you accidentally type “myjarfile.jar” or “myJarfile.jar,” the operating system will not be able to find the file and execute it.
- Error unable to access jarfile /app.jar kubernetes.
- Error unable to access jarfile server jar minehut.
- Error: unable to access jarfile agent.jar jenkins.
- Java virtual machine launcher error: unable to access jarfile.
- Error from tabula-java: error: unable to access jarfile.
– Permissions Issue
The permissions issue error message can occur when the Java application does not have sufficient permissions to access or execute the JAR file.
In most operating systems, files have permissions determining who can read, write, and execute them. If you run the Java application and it does not have the appropriate permissions to access the JAR file, the “unable to access jarfile” error message will appear.
– The JAR File Is Corrupted
Another cause of the error can be when the JAR file is corrupted. This error message can occur when the JAR file itself is damaged or incomplete. When a JAR file is corrupted, it means that some parts of the file are missing or the file is not in the expected format.
The unable to access jarfile error message is one indication that the JAR file may be corrupted. Other symptoms may include unexpected behavior or error messages when running the Java application.
– Missing Dependencies
The missing dependencies error message can occur when a Java application requires one or more external libraries or dependencies to run correctly, but they are not present in the system. A dependency is a piece of code or software that is required by another program to function correctly.
Java applications often use external libraries or dependencies to provide additional functionality or access to specific resources. When a Java application is executed, it checks for the presence of these dependencies in the system, and if they are missing, it can result in the unable to access jarfile error message.
– Default Program Causing Issues
Sometimes, the default program or default file causes the error to arise. This error message is related to Java and the Java Virtual Machine (JVM) and occurs when the JVM is unable to read or open jar file specified in a command-line script or application. The error message usually appears in the command prompt or terminal window when the program is executed.
– Hidden Files Causing Issues
Hidden files may be relevant in the context of resolving the “Unable to access jarfile” error message if the jar file or any of the directories in the file path are hidden. Hidden files or directories are files or directories that are not displayed by default in the file explorer or command-line interface and are often used to store configuration or system files.
If any of the directories in the file path to the jar file are hidden, the JVM may not be able to find the file and resulting in the error message. To check for any hidden directories in the file path, you can use the “dir” command in the command prompt or terminal, with the “/a” parameter to show hidden files and directories: dir /a. If any of the directories in the file path are hidden, you may need to unhide them using the file explorer or the “attrib” command in the command prompt or terminal: attrib -h path\to\directory.
– Minecraft Server Causing Issues
The Minecraft server is not directly related to the “Unable to access jarfile” error message discussed in this article. However, the error message may occur when trying to run a Minecraft server if the server’s configuration or startup script references a jar file that the JVM is unable to access or read.
When setting up a Minecraft server, the server’s configuration or startup script typically specifies the location of the Minecraft server’s jar file. If the jar file is not located in the specified location, or if the file path contains errors, the JVM may not be able to access the file and result in the unable to access jarfile error message.
How To Resolve the Unable to Access Jarfile Error Message?
To resolve the unable to access jarfile error, users can check the file path and name, ensure that the jar file is in the same directory as the command line script, and verify that the jar file is not corrupted.
– Check the File Path
When we say “Check the file path” in the context of resolving the unable to access jarfile error message, we mean verifying that the path to the jar file is correct.
The path is a series of directories that lead to the file. If the path is incorrect, the JVM (Java Virtual Machine) will not be able to locate the jar file which will result in the error message.
To check the file path, you need to ensure that the path you are specifying in the command line is correct. You should verify that the directory structure is accurate and that each directory in the path exists. You should also make sure that the path separator character used in the command line matches the one used by your operating system.
For example, if your jar file is located in the “myproject” directory, which is located in the “Documents” directory on your computer, the file path would be:
C:\Users\yourusername\Documents\myproject\myfile.jar
It is important to ensure that the file path is spelt correctly and that you are using the correct case for any directories or filenames. If you are unsure of the correct file path, you can use the “cd” command in the command prompt to navigate to the directory where the jar file is located and then use the “dir” command to see the contents of the directory.
By verifying that the file path is correct, you can eliminate one potential cause of the unable to access jarfile error messages and increase the chances of successfully running your Java program.
– Check the File Name
“Check the file name” in the context of resolving the “Unable to access jarfile” error message; we mean verifying that the jar file name is spelt correctly and that it has the correct file extension.
The jar file name should be spelt exactly as it appears on your computer, including any uppercase or lowercase letters. If there is a typo in the file name, the JVM (Java Virtual Machine) will not be able to find the file which will result in the error message.
In addition, the file extension of the jar file should be “.jar”. If the file extension is incorrect, the JVM will not recognize the file as a jar file and will result in an error message.
To check the file name, you should navigate to the directory where the jar file is located and check the spelling of the file name and its file extension. If you are unsure of the correct file name or file extension, you can use the “dir” command in the command prompt to see a list of files in the directory.
– Jar File Should Be in the Same Directory as the Command Line Script
When you try to run a jar file from the command line, you need to specify the file path to the jar file. If the jar file is not located in the same directory as the script that is trying to run it, you need to specify the full path to the file.
To check if the jar file is in the same directory as the command line script, you should navigate to the directory where the script is located and verify that the jar file is also located in that directory. If the jar file is not located in the same directory, you should move the file to the correct directory or specify the full path to the file in the command line.
– Check if the Jar File Is Corrupted
If the jar files are damaged or corrupted, the JVM (Java Virtual Machine) may not be able to read the file, resulting in the error message.
To check if the jar file is corrupted, you should try to open the file in file archiving software, such as WinZip or 7-Zip, and verify that the contents of the file are intact. If the file is damaged or corrupted, you may need to download the file again from a reliable source or retrieve a backup copy of the file.
– Check if Java Is Installed
Ensure that Java is installed on your system and that the JAVA_HOME environment variable is set. If Java is not installed or the environment variable is not set, the JVM will not be able to run the jar file.
Conclusion
After reading this article, the reader can now resolve this error message on their own with a proper understanding of this error message. Some key takeaways from the article that will help you fix this error are:
