   Preondition Violations

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

   Preondition Violations
   Unmatched statement workspaceFile=ResourcesPlugin.getWorkspace().getRoot().getFile(new Path(getLocation())); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted
