[platform-dev] NoClassDefFoundError for IJavaProject in a Plugin

[Torsten Schlabach <tschlabach@xxxxxxx>]

Hi!

I am somewhat new to Plugin development, and I am not sure if this 
mailing list is the appropriate place to ask, so feel free to redirect me.

My problem is this:

I have written a plugin which is trying to use the interface

org.eclipse.jdt.core.IJavaProkject

My Plugin dependencies contain

org.eclipse.jdt.core

and the plugin compiles fine.

Just at runtime (when using the plugin) all the classes from JDT core 
seem to be invisible to the classloader.

JDT is enabled in the workspace in which I am trying to use my plugin. 
At least I'd guess so because I have opened some project which have a 
Java Nature.

Any hints?

Regards,
Torsten
