This is a cross post from the GEF forum. One of the GEF guys suggested I post my topic here because the current problem is javafx related, which GEF5 is tightly integrated with. Here is the original post:

I have a large commercial application that used to be Eclipse RCP 3.x with GEF 3.x. I've transitioned it to a pure e4 RCP application and I'm trying to make it work with the latest GEF 5. I have been struggling with JavaFX and GEF 5 for a while now. To try and work the problem, I set out to create a small working example that can help me and hopefully others understand how to configure an e4 application with GEF 5. I also have a subsequent goal of building the whole thing with a headless Tycho build.

I am currently stuck and I hope to get some help to make this proof of concept application work. You can check it out here: https://github.com/kjkeefe/e4gef5shapes

The README explains how to get it imported and running (although it is broken with a javafx problem). The README also shows the current sticking point.

Please let me know if you have any questions or ideas for how to improve this example. If you can help just get me past the current error, I can spend some more cycles on the next steps.

Thanks,
Ken

As Tom pointed out over on the other post, I am trying to bundle the javafx libraries in my own bundles so that when I distribute my application, my users don't need to install JavaFX first and my application doesn't need to perform some discovery of the JavaFX libraries and configure the eclipse.ini to point to the right path. Bundling it like this seemed like a simpler solution, but it looks like I am missing something.

I try to clone your repo in the next few days and see what I can find. In general we advise people to not repackage javafx but use the adapter-hooks from efxclipse because then JavaFX runs as a JPMS-Module which is the only officially supported way.

I am happy to do it any way that you recommend. I just don't want to require my users to install something before my software is installed. It'd be great if there was a simple Maven dependency or Eclipse feature I could include in my product definition. Thank you for working on it.
