Anyone ever got JavaFXPorts working for android?

I have spend two days trying to get JavaFXPorts working for android, without any luck. Gluon’s documentation on how it works is very poor, and contradicts itself in so many places. I have tried their gradle plugin. I cannot get even a simple build to work.

Has anyone here ever got this working, or tried? I cannot even get their example repos to work.

Thanks,
Trevor
