I have written a plug-in with an editor that extends the EMF .genmodel
Editor (org.eclipse.emf.codegen.ecore.genmodel.presentation.GenMode lEditor
class). The plug-in worked fine under Eclipse 2.1.2 and EMF 1.1, but after
migrating it to Eclipse 3.0 (Release ID: 200406251208), when trying to
load it I get a ClassNotFoundException.
This occurs both when I try to migrate my plug-in manually and when using
the PDE Tool Migrate to 3.0. I've checked the plugin.xml file, the class
names, dependencies, etc. to no avail.
Anybody knows what may be happening here?
Below the plugin.xml and the .log
Thanks in advance,
Mariana

Problem solved!
My plug-in started working as soon as I erased the
"org.eclipse.core.runtime.compatibility" plug-in from the dependencies.
From reading the migration guide and similar it is not clear to me why
this would happen, though.
