Hello,
I’m having the same problem. Tried everything with jdk 11, 12 and the javafx versions; Even tho i’m setting the Run Configurations and library and everything, it just doesn’t seem to be able to run an application properly.
Also it’s not some setting problem on intellij, i also properly installed eclipse and didn’t work there either.

If you find any solution for the problem i would be glad to hear it.

I’m closing this issue due to lack of details or a way to reproduce it. Feel free to open it again with the required information.

i guess you added the javafx.base in the VM options when it wasn’t existing in the file where your javafx version is installed .

go check if it’s installed or not , if it isn’t download it and the drag drop it in there

Did anyone ever figure this out? Still lost. Same issues after following constant tutorials.

Yes. I’m getting the same error.

This is a closed issue, but it can be opened again, if anyone provides more details on how to reproduce it.
@jesusCDev. @imrsk please provide exact details of how you are trying: IDE, OS, Java/JavaFX versions, type of sample (modular/non-modular, IDE, maven or gradle), how do you set the VM options, the Java Command line, and the exception you get,

oops. It’s a really silly mistake. My apologies, @jperedadnr . And @jesusCDev , if you are using linux, remove the $ before the path and keep your VM options like

—module-path /home/local/Downloads/openjfx-11.0.2_linux-x64_bin-sdk/javafx-sdk-11.0.2/lib —add-modules=javafx.controls,javafx.fxml

I followed leelakarthik’s comment above and added $ by mistake.

@imrsk Thank you! This worked perfectly!

I’m still having this same issue (mine complains about javafx.controls), but the issue is the same. I followed: https://openjfx.io/openjfx-docs/#install-javafx for NetBeans with the non-module instructions.

I’m on Windows 10, NetBeans 11.1 and using JDK and JavaFX 13.

When it finally gets to the —module-path and —add-modules arguments instructions, I follow those and get the error:

Error occurred during initialization of boot layer
java.lang.module.FindException: Module javafx.controls not found
C:\Users\jpbau\AppData\Local\NetBeans\Cache\11.1\executor-snippets\run.xml:111: The following error occurred while executing this line:
C:\Users\jpbau\AppData\Local\NetBeans\Cache\11.1\executor-snippets\run.xml:68: Java returned: 1

Any updates on this?

profjpbaugh, in the VM options in this line :
—module-path «\path\to\javafx-sdk-12\lib» —add-modules javafx.controls,javafx.fxml
did you changed the path «\path\to\javafx-sdk-12\lib» to your local path where javafx sdk exist?

Hello,

please note under NetBeans, it is extremely important to turn off the ‘Compile on Save’ options under the Project Properties -> Build -> Compiling.

If it is switched on an error message appears:
Error occurred during initialization of boot layer
java.lang.module.FindException: Module javafx.controls not found

Hi @Smurfi,

This fixed my problem that I’ve been working on for several days! I’m not sure why this little piece isn’t in any of the tutorials I looked at on how to set up javaFX for netbeans, but it absolutely wouldn’t run without it. Thanks so much!

Wow!

Hello @Smurfi

Thank you so much for the tip. I have been having the same issue as others here and I have been looking around for a solution for the past day. Unchecking that option completely fixed it and I can now run my JavaFX code in Netbeans.

I really appreciate it. This entire time I thought I was missing something in the tutorials I checked out.

@trondag

Are you using netbeans or something else? You right click the project and go to properties, then to build in netbeans.

Just make sure that your path in module path is correct.. Copy path from libraries in project structure.For me it worked

@Lodisy12
Is there a similar setting in Intellij that could be causing me issues like this? I am at a loss and don’t know what do do about this problem.

Hi @DaveAvid,
I don’t use IntelliJ personally, so I haven’t done any troubleshooting for myself. Have you followed the step by step tutorial from https://openjfx.io/openjfx-docs/#IDE-Intellij ?
That would be my first suggestion if you haven’t. If you have, my other suggestion would be to give NetBeans a chance. I know a lot of people who hate it, and a lot of people who love it, but I think it’s pretty good.

Hi @Smurfi,
I turned off the compile on save option like you said, but i’m still getting the same error occured … module javafx.controls not found message. Do you know why this could be? I followed the tutorial for a non modular project: https://openjfx.io/openjfx-docs/#maven

What helped me: set VM Options and Project Properties > Compile > Modulepath > + > just added all jar files from the javafx-sdk/lib folder. And you could leave Compile and Save checked

@DaveAvid did you ever figure out the intellij equivalent? I have been trying to fix this for days and can’t figure it out

I figured out my issue and its working now! I am using Windows but my fix was similar to the Linux solution. In my case i was trying to use —module-path %PATH_TO_FX% and for some reason the % was not escaping. For the very short term i have replaced it with a hard coded path to the javafx/lib so i can finish another sprint issue that involves another team member and is more of an immediate priority. That being said, hard coded paths are obviously never the production solution so i will keep you updated with a permanent fix when i get around to it on Monday.

oops. It’s a really silly mistake. My apologies, @jperedadnr . And @jesusCDev , if you are using linux, remove the $ before the path and keep your VM options like

—module-path /home/local/Downloads/openjfx-11.0.2_linux-x64_bin-sdk/javafx-sdk-11.0.2/lib —add-modules=javafx.controls,javafx.fxml

I followed leelakarthik’s comment above and added $ by mistake.

this works Thanks

Hi
please make sure when you set vm options that you change module path to your JDK lib path and delete the extra 2 » if you copying from windows 10.

• Note (Linux UBUNTU): Make sure you don’t add the src.zip file, as it will cause an exception when running the project. (By Adding Library)

«Compile on Save (requires nb-javac plugin)»
I installed the nb-javac plugin after getting a notification in the status bar of NetBeans, saying:
«Install nb-javac Library»
So I guess after installation of that plugin, the «Compile on Save» option was activated, and then I got this error message when trying to run the project:
«Error occurred during initialization of boot layer
java.lang.module.FindException: Module javafx.controls not found»

Thank you so much, Smurfi!

** If you are having this error on Eclipse**
«Error occurred during initialization of boot layer
java.lang.module.FindException: Module javafx.controls not found»

Remove the JavaFX SDK library from the build path of the project!!

@NathanPaceydev I am still facing the issue. Do I need to turn on the «Compile on Save» in Eclipse as well? If yes, where can I find it?

profjpbaugh, in the VM options in this line :
—module-path «\path\to\javafx-sdk-12\lib» —add-modules javafx.controls,javafx.fxml
did you changed the path «\path\to\javafx-sdk-12\lib» to your local path where javafx sdk exist?

Guys I figured it out! Delete the src.zip file when u get the error:

(NOTE: I am a total noob in markdown. I tried )

java.lang.module.FindException: Module format not recognized: C:\(PATH_TO_FX)\lib\src.zip

Process finished with exit code 1````

**Then it works!!** 

@NathanPaceydev I am still facing the issue. Do I need to turn on the «Compile on Save» in Eclipse as well? If yes, where can I find it?

You do not need to turn on Compile and Save. Make sure you have the correct VM arguments and you have downloaded the correct SDK library to run JavaFx. Hope that helps.

In eclipse go to build path in the project folder > configure build path > click modulepath > add external JARS > select all jar files in javafx lib folder

Thanks a lot, that hit the spot. I was almost going crazy. Works on Eclipse 2021-03, Open JDK 16 on Ubuntu 21.10! great stuff!

Glad I could help, this problem was driving me crazy too!!

I have same problem with my Eclipse. I dont know to do with this. Please Help me!!!!

you need to put copy the javafx files from your computer to eclipse and
make a user library then add this library to the build path of your project

…

anybody could make it work on intellij? i keep getting this error message: «Error: Could not find or load main class javafx.fxml
Caused by: java.lang.ClassNotFoundException: javafx.fxml», even tho i included javafx.controls and javafa.fxml on VM options.

could you elaborate more? im having trouble doing the same process on intellij

I find that version 1.8 could be able to run on eclipse and each of the java projects might have a deviation between the java project category.

if you use IntelliJ , you must delete module-info.java in src/main/java, i did and it works,
this file is automatically generated when you create javafx project

Okay so I narrowed it down and got it to run.

Verified on: Intellij IDEA on M1 Macbook pro

Hypothesis:

The javafx helloworld tutorial incorrectly gives us the following VM options for «Linux/Mac» found here : https://openjfx.io/openjfx-docs/#maven. This is missing the equals «=» operator.

• Incorrect Copy/Paste Line «—module-path /path/to/javafx-sdk-19/lib —add-modules javafx.controls,javafx.fxml»

Fix:

1. Run > Edit Configurations > Select «Application» configuration > Under Build and Run > Select «modify options» > Under «java» Select «add VM Options

2. VM Options, you will need to customize this to your local machine :

—module-path=/Users/USERNAMEHERE/FOLDERWITHSDK/java-sdk-19/lib —add-modules=javafx.controls,javafx.fxml

1. This is the correct format for MAC formatting to the VM Options.

One more possible solution. If you use Gluon Gradle plugin and java module system and seems that everything is right, look at your automatically created build.gradle file:

application {
  //mainModule = 'net.snatchlab.photoframe'
  mainClass = 'net.snatchlab.photoframe.PhotoFrameApplication'
}
mainClassName = 'net.snatchlab.photoframe.PhotoFrameApplication'

It’s important to remove/comment specifying ‘mainModule‘ in the ‘application‘ section. Maybe the whole ‘application‘ section is not needed, didn’t try to remove it yet.

My problem was about javafx.controls, not javafx.base. This module was declared in the build.gradle:

javafx {
  version = '17'
  modules = ['javafx.controls', 'javafx.fxml']
}

and in the module-info.java:
requires javafx.controls;

Commenting ‘mainModule‘ solved the issue without specifying VM options.

Alternatively, you can select JavaFX SDK under Modulepath and click on Remove icon on the right side and it will work without adding those external JARS. I have tried it and this also worked for me.

Hello,

Im having the same issue as some of you in MAC, I get this error: Error occurred during initialization of boot layer
java.lang.module.FindException: Module javafx.base not found

Im trying to set it up in intellij, I have used. the recommended path:
—module-path=/Users/USERNAMEHERE/FOLDERWITHSDK/java-sdk-19/lib —add-modules=javafx.controls,javafx.fxml
This is what im using:
—module-path=/Users/NAME/Desktop/javafx-sdk-20.0.2/lib/
—add modules=javafx.controls,javafx.fxml,javafx.graphics,javafx.base

Also, added the library as instrusted. I tried using the version of javafx SDK x64 and arch64 from Gluon and it doesn’t work.
Not sure what else I could do. I would appreciate any help.

Regards.
