Re: [jdt-core-dev] Java9 Beta Branch
I assume you did add the javafx module(s) to your module file, e.g.

requires javafx.base;

If yes, and if it is not working as expected then please file a bug against JDT Core.

Hi,

Ok so now that I can at least create a simple HelloWorld. I tried to use
JavaFX but it looks like I can not reference any of the classes in the
javafx-modules.

On the other hand I can reference things like JPanel, ... . Is there
anything special I need to do to reference those classes.

Having access to javafx-modules is of high importance for us because we
need to make sure e(fx)clipse is compatible with JDK9. This does not
only affect e(fx)clipse who is part of the release train but also other
projects like GEF4 who depend on us.
