I get the following error:

$ ./gradlew build

FAILURE: Build failed with an exception.

* What went wrong:
java.lang.UnsupportedClassVersionError: org/openjfx/gradle/JavaFXPlugin has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

See if you can use OpenJDK 11 to run this. There have been issues with newer versions of OpenJDK that cause it to just completely fail to run.

Thanks for the reply. I will delete the newer version and try the older one.

Edit:

Same error.

Here is the Java 11 pkg installed and removed Java 17:

Looks like I may need to spin up an instance of FreeBSD to debug this. I have just gotten an ubuntu install re-created to add G640 compatibility. Will need more time or another volunteer to check out what is going on in FreeBSD.
