   Preondition Violations

   Type org.eclipse.emf.ecore.provider.EAttributeItemProvider of variable eAttributeItemProvider does not match with type org.eclipse.core.resources.ResourceAttributes of variable resourceAttributes
   - Make classes org.eclipse.emf.ecore.provider.EAttributeItemProvider and org.eclipse.core.resources.ResourceAttributes extend a common superclass

   Preondition Violations
   Unmatched statement eAttributeItemProvider=new EAttributeItemProvider(this); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted
