Tumbleweed release : 20200831-678.1
Package : openjfx (11.0.8-1.2), openjfx-devel (11.0.8-1.2)
Issue : The JAR file javafx-graphics.jar is empty and has no javafx-*-linux.jar like the others. Unable to build any JavaFX projects. I am aware of the alternative of using the JavaFX from Gluon, but it would nice if this was fixed.
Hi and welcome to the Forum 
If you check the build log it’s there and the others, perhaps a different location that you are expecting?

Ah yes, there it is. I was expecting it to be under /usr/share/java/openjfx/ like the rest of them. Seems rather odd to have just that one JAR placed in /usr/lib64/openjfx while the rest are where they are expected.
Nevertheless, the proper way of using them seems to be using the symlinks under /usr/share/openjfx/lib/ [FONT=arial]which unfortunately don’t dereference properly if one is using an Eclipse flatpak. Symlinks work fine under regular Eclipse install using the Eclipse Installer.
Seems to be a flatpak issue after all and not the openjfx maintainer’s fault.
Thanks![/FONT]
