   Preondition Violations

   Type org.eclipse.core.resources.IProject of variable project does not match with type org.eclipse.emf.ecore.EStructuralFeature[] of variable eAllStructuralFeaturesData
   - Make classes org.eclipse.core.resources.IProject and org.eclipse.emf.ecore.EStructuralFeature[] extend a common superclass
