Having annotated java extend other external interfaces [message #530907]

Is there any way to preserve in code generation (from annotated java) inheritance from all other java interfaces, both hand coded and regular (like Serializable)? If not, how to preserve manually added interfaces in generated code when you re-generate?

So I have something like:

import my.other.stuff.Abra;
import java.io.Serializable;
/**
* @model
*/
public interface Link extends Abra, Serializable
{...}

After code generation I still have Abra, but Serializable gone, I got

import my.other.stuff.Abra;
import org.eclipse.emf.ecore.EObject;
/**
* @model
*/
public interface Link extends EObject, Abra
{...}

Note that EObject does not extend Serializable

Alexey,

You can use @extends or @implements so that the merger will add in stuff
that's not part of the actual model. I'm surprised you didn't end up
with an EClass wrapper for java.io.Serializable in your model though...
