How to fix jfoenix modules with javafx 11

Question

So I'm adding my requires for module-info.java and finally got my program to load but as soon as tab pane wants to load from jfoenix library this error is thrown.

Caused by: java.lang.IllegalAccessError: class com.jfoenix.skins.JFXTabPaneSkin (in module com.jfoenix) cannot access class com.sun.javafx.scene.control.behavior.TabPaneBehavior (in module javafx.controls) because module javafx.controls does not export com.sun.javafx.scene.control.behavior to module com.jfoenix

One way you can try fixing this is by adding the vm option for the required export:

--add-exports javafx.controls/com.sun.javafx.scene.control.behavior=com.jfoenix

The ideal solution to that would be the jfoenix library to move away from using com.sun.javafx.scene.control.behavior.TabPaneBehavior.

I added to vm option and I'm now getting Caused by: java.lang.IllegalAccessError: class com.jfoenix.skins.JFXTabPaneSkin$TabHeaderContainer (in module com.jfoenix) cannot access class com.sun.javafx.scene.control.LambdaMultiplePropertyChangeListenerHandler (in module javafx.controls) because module javafx.controls does not export com.sun.javafx.scene.control to module com.jfoenix – exceptionsAreBad Nov 28 '18 at 19:39

I was able to successfully run every aspect of the jfoenix library thus far. I still have some testing to do in my application to make sure there are no errors hidden but at this moment the following VM options fixed the issue :

--add-exports javafx.controls/com.sun.javafx.scene.control.behavior=com.jfoenix
--add-exports javafx.controls/com.sun.javafx.scene.control=com.jfoenix
--add-exports javafx.base/com.sun.javafx.binding=com.jfoenix
--add-exports javafx.graphics/com.sun.javafx.stage=com.jfoenix
--add-exports javafx.base/com.sun.javafx.event=com.jfoenix

Is it possible to do that if I'm using a module-info.java for my project? – fegemo May 04 '20 at 15:46

folks if you still get error try adding this ```--add-opens java.base/java.lang.reflect=com.jfoenix``` – Tanmay jain Feb 08 '21 at 12:23

An alternative to all this module pain is to completely abandon the JPMS and put all libraries (also JavaFX) on the classpath and then start your application via a launcher like this:

class MyAppLauncher {public static void main(String[] args) {MyApp.main(args);}}

Note that, while this will likely work for most JavaFX apps running on JavaFX 11-17 (and is way easier than dealing with JPMS modules), running JavaFX on the classpath isn't a configuration supported by the JavaFX development team, so this approach is not guaranteed to work for new JavaFX release (and, for recent JavaFX releases, will generate a warning at runtime, then continue to happily execute). – jewelsea Sep 29 '21 at 18:51

If they ever make that really fail this will be the day when I quit supporting and using JavaFX. I have better things to do than spending my time fighting with the module system. – mipa Sep 30 '21 at 07:32

Please try this, it works for me. I hope it will be useful for you too.

--module-path "D:\Libs\javafx-sdk-11.0.2\lib"  
--add-modules javafx.base,javafx.controls,javafx.fxml,javafx.graphics
--add-opens javafx.controls/com.sun.javafx.scene.control=ALL-UNNAMED
--add-opens javafx.controls/com.sun.javafx.scene.control.behavior=ALL-UNNAMED
