Henrich,
Since your model references Ecore directly, your edit project is assumed to need references to the
Ecore edit project and so a project reference and classpath entry will be created for it. And if you
need to reference the ecore.edit stuff, you need to bring the ecore.edit project into the workspace
with the right _x.y.z suffix (as is specified by the Edit Project information in the Ecore.genmodel).
We've been talking internally about being able to reference .genmodel/.ecore files directly from a
binary project rather than having to bring it into the workspace, but we haven't done any real work on
this yet...
