   Preondition Violations

   Type java.util.List<org.eclipse.emf.edit.provider.IItemPropertyDescriptor> of variable itemPropertyDescriptors does not match with type org.eclipse.core.resources.IProject of variable project
   - Make classes java.util.List and org.eclipse.core.resources.IProject extend a common superclass
