How do I fix the controlsfx demo program to initialize class org.controlsfx.glyphfont.FontAwesome?

Question

The controlsfx JavaFX library has a demo program and some controls fail to run, such as List Selection View, or List Action View or BreadCrumbBar.

I re-tested this on a new Windows 10 PC, with JDK11 and Gradle 5.5 freshly installed. I downloaded the branch 9 .zip, verified that the module-info.java files are present, and entered

gradlew run

For the above mentioned examples, the console shows:

Exception in thread "JavaFX Application Thread" java.lang.NoClassDefFoundError: Could not initialize class org.controlsfx.glyphfont.FontAwesome
        at org.controlsfx.samples/org.controlsfx.samples.HelloListActionView.createActions(HelloListActionView.java:144)

JAVA_HOME is C:\Program Files\Java\jdk-11.0.3

gradle --version

I'd like to take advantage of FontAwesome as well as the above mentioned controls.

I experimented with JDK 11, 11.0.1, 11.0.2, 11.0.2 Gradle 5.2, 5.5 Command line IntelliJ Another PC I usually develop on

Hi, did you manage to fix this? I have the same issue – Alessandro Roaro Oct 17 '19 at 10:30 — Alessandro Roaro, Oct 17 '19 at 10:30

ControlsFX has a large number of external dependencies which are handled in the build.gradle file.

If your project does not use gradle to build the library, but instead it imports a .jar of it, then you should add all those options to the VM. To do that in IntelliJ, go to Edit Configuration, there you can find a VM options field.

You can try to copy and paste these options:

--add-exports=javafx.graphics/com.sun.javafx.scene=org.controlsfx.controls --add-exports=javafx.graphics/com.sun.javafx.scene.traversal=org.controlsfx.controls --add-exports=javafx.graphics/com.sun.javafx.css=org.controlsfx.controls --add-exports=javafx.controls/com.sun.javafx.scene.control.behavior=org.controlsfx.controls --add-exports=javafx.controls/com.sun.javafx.scene.control=org.controlsfx.controls --add-exports=javafx.controls/com.sun.javafx.scene.control.inputmap=org.controlsfx.controls --add-exports=javafx.base/com.sun.javafx.event=org.controlsfx.controls --add-exports=javafx.base/com.sun.javafx.collections=org.controlsfx.controls --add-exports=javafx.base/com.sun.javafx.runtime=org.controlsfx.controls --add-exports=javafx.web/com.sun.webkit=org.controlsfx.controls --add-exports=javafx.graphics/com.sun.javafx.css=org.controlsfx.controls

This worked for me. I was facing the same issue with ControlsFX 11.0, while using ListSelectionView.

How do I fix the controlsfx demo program to initialize class org.controlsfx.glyphfont.FontAwesome?
