JavaFX Modular Application, java.lang.module.FindException: Module javafx.controls not found (Java 11, Intellij)

Question

I have a problem with my modular JavaFX application. I created a JavaFX project and added the JavaFX lib and JavaFX modules get recognized. However, I keep getting these error message:

Error occurred during initialization of boot layer
java.lang.module.FindException: Module javafx.controls not found

Image for the complete setup is attached hereby:

edit:

this is all the errors messages:

I also add the vm options:

but still, i got this error messages.

Solution

Since you're running as a Non-Modular application from IntelliJ, you would need to ensure adding the VM argument as :

--module-path /path/to/javafx-sdk-11.0.1/lib --add-modules=javafx.controls,javafx.fxml

You can follow the documentation link as JavaFX and IntelliJ and then Non-modular from IDE for complete setup details.

Thank you for the answer, but I have following these step and still get error.

@rizkyramadhan In which case, could you expand the command line as visible in the terminal of IntelliJ and update with the same in the question? (The green highlighted line on your terminal ending with an ellipsis...)

I've edited the post and put all the error messages. you know, I tried javafx on my windows 10 and it works perfectly, but I'm not always using windows, for a daily basis, I use Ubuntu 18.04 and it doesn't work. Hmm.

For anyone else having issues, this worked for me: as Naman said.. --module-path "C:\Program Files\Java\javafx-sdk-11.0.2\lib" --add-modules=javafx.controls,javafx.fxml

I've got the same issue, and the problem was with the correct path to the javafx-sdk. In this case, you should update the path after unpacking javafx-sdk to the system very attentively!
