[Modelinterpreter] [Model Interpreter] #223: Building workspace fails

Fri May 29 13:25:55 CEST 2015

Ez nem builder specifikus hibának tűnik... Mintha class fájlok 
hiányoznának. A ResourceException-ök nem érdekesek, azóta le is lettek 
tiltva. Az első értelmes exception viszont okozhatja a többit:

  org.eclipse.emf.ecore.xmi.ClassNotFoundException: Class 'EAnnotation' is
  not found or is abstract. (platform:/resource/execute/test9.uml, 73, 128)
