Hello everybody,
working with UML2Ecore from a Papyrus Class Diagram, I get duplicated @Override on the getter and setter of redefined properties in the generated code (I'm redefining properties in my UML model, just to redefine the multiplicity from 0..1 to 1..1 ).

Is it a know bug ? is there a way to avoid this bad behavior ?

In attachement, a small model close to my real one, allowing to reproduce my bug.

I set Duplicated Feature Inheritance, Duplicated Feature and Redefining Properties to Process in my UML genmodel.

index.php/fa/35600/0/

Thank your for your help.

Hi

EMF code generation gradually evolves. A recent (since Photon) change is the addition of fuller Java 6 @Overrides annotations. It is possible that the changes to EMF JET templates have not been duplicated in the similar UML JET templates leading to an uncomfortable mix. Please raise an Eclipse UML2 bug.

Workaround, set the GenModel Java compatibility level to Java 5 so that there are no @Overrides at all.

Regards

Yes, EMF now generates @Override where they are required for Java 6 compatibility, i.e., for methods that override an interface method. Those are generated only when Java compatibility is set to Java 8 or higher. Of course for Java 5 compatibility EMF continues to generate @Override, but only for methods that override another class' method, so as Ed suggests, changing the compatibility is a temporary workaround.

It is like that UML2's templates generate @Override for methods conditionally for cases where the base EMF templates also generates that in the case of Java 6 compatibility. UML2 will need to change their templates to adjust. It would be good to open a Bugzilla for UML2, along with a simple test case.

Hi Ed, thank you for your answer. I fill the bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=547424.

I found another workaround to this bug: I add these GenModel EAnnotation to my redefining properties (so the properties of the class Mandatory**Representation in my example).

suppressedGetVisibility -> true
suppressedSetVisibility -> true

It seems me it work find with that.
