Add JavaFX jmods to java –list-modules


I need to open .jar files which requires Java and JavaFX. I have installed both Java (from Oracle website) and JavaFX (SDK from openjfx website). I have added environment variables by updating /etc/environment file, and adding JAVAFX_HOME="path/to/JavaFX".

/etc/environment file looks like:


For now, I can get a .jar file running by executing:

java --module-path $JAVAFX_HOME --add-modules ALL-MODULE-PATH -jar myfile.jar

There are multiple .jar files, which makes executing above command pretty troublesome. Name of .jar files are pretty non-catchy and complex too.


I want to know if I can add JavaFX jmods to Java permanently. For example, when we execute in terminal java --list-modules, it should include JavaFX mods in it too.

I have tried:

  1. Copying JavaFX jmod files in /usr/lib/jvm/jdk-12.0.2/jmods. But even after rebooting, java --list-modules doesn’t include JavaFX mods. I have also ran
    sudo update-alternatives --config java 
    sudo update-alternatives --config javac
  1. I don’t think creating .sh script files would be a great idea as there would need to be as many script files as there are .jar files.

Any help is highly appreciated. I am on Kubuntu.



You can use environment variable: _JAVA_OPTIONS. All options specified in this variable will be appended to the JVM startup args.

export _JAVA_OPTIONS="--module-path=/path/to/JavaFX --add-modules=ALL-MODULE-PATH"
