I am upgrading my eclipse ide to Eclipse 2019-06. My project is a large RCP project with about 50 plugins and 20 features. Three of my plugins use GEF and FX. These plugins no longer seem to be building correctly.

I get the same errors in all three of the plugins:

The type javafx.embed.swt.FXCanvas cannot be resolved. It is indirectly referenced from required .class files	ADVISEGEFModule.java	/edu.illinois.mobius.atomic.advise/src/edu/illinois/mobius/atomic/advise/ui/gef	line 1	Java Problem

The project was not built since its build path is incomplete. Cannot find the class file for javafx.embed.swt.FXCanvas. Fix the build path then try building this project	edu.illinois.mobius.atomic.advise		Unknown	Java Problem

This is the target file that I'm using:

I was finally able to resolve this problem by following the instructions here to manually add jfxswt.jar to my JRE Eclipse configuration...
