Eclipse plugin with JOGL - ClassNotFoundException

I'm trying to create a eclipse plugin which uses JOGL to display some editor contents.

I packaged the required libraries (JOGL, Nativewindow and Gluegen) each into their own plugin and added all three plugins to the dependency of my editor plugin.

Now if I try to setup an OpenGL display and implement the GLEventListener I always get the following exception in the Eclipse error log upon loading the class which does the OpenGL calls:

java.lang.NoClassDefFoundError: com/jogamp/common/type/WriteCloneable

(full stack below)

I tracked down that class and it is located inside the Gluegen dependency and I can even open the class using the "Open type" dialog in eclipse and still eclipse doesn't seem to be able to find it.

I created the plugin project for the libraries using the "Plug-in from Existing JAR Archives" wizard inside Eclipse and I also double-checked the exported packages and they do contain the package which can't be found.

Now, does anyone know what I'm doing wrong?

Full stacktrace:

I somehow solved my own problem. I'll explain what the problem was:
I discovered that every library has to have the libraries it depends on added to its dependencies too. With JOGL that means that you have to add both Nativewindow and Gluegen as a dependency to the JOGL plugin and you also have to add Gluegen as a dependency to Nativewindow.

Are you building a jar for your eclipse plugin? Can you look inside this generated jar for the
gluegen-rt.jar respectively for the com/jogamp/common/type/WriteCloneable.class ?

Perhaps you can build the jar with maven and the jar or assembly plugin to include the gluegen-rt.jar
