codegen.ecore is not generating @Override annotations in Java 10+ compliance levels

[subagergely]

It seems the reason of this issue is in GenModelImpl.getComplianceLevel(URI uri) function, which is not handling Java 10+ compliance levels. It returns the default Java 5 compliance level in these cases:

Note that you can modify the generated .genmodel or specify in the .xcore the compliance level. This method only computes a good default form the information in the project.

When this build finishes:

the fix will be available here:

Thanks for the quick answer and solution! Following your suggestion, the xcore complianceLevel setting also solved the problem: @GenModel(complianceLevel="17.0")
