Xcore referencing another xcore => Same name URI for Ecore.ecore [message #1097950]

Hello,

I have defined an xcore A in project A and an xcore B in project B. In both project I generate the corresponding ecore and genmodel.

Inside xcore B, I import a class CA found in A then I define a new class extending CA.

Problem: I get an error inside the genmodel for B:
"The package 'archive:/file:/<emfJarPath>/model/Ecore.ecore#' has the same namespace URI 'http://www.eclipse.org/emf/2002/Ecore' as package 'platform:/plugin/org.eclipse.emf.ecore/model/Ecore.ecore#/'

I get no error if I don't reference A. Also in the genmodel wizard, in Referenced generator models, I select Ecore('org.eclipse.emf.ecore' plugin) and not Ecore(archive:/file:/<emfJarPath>/model/Ecore.genmodel) which is selected by default. I don't want to have hardcoded local paths.

I have no idea what's the problem, can you help?
Thanks a lot!
Sébastien

Why do you generated an Ecore and GenModel? Indexing is likely to get
confused by the presence of both the *.genmodel and the *.xcore defining
the same model with the same nsURI.

How did you set up the classpath for each of the two projects?

Sounds like an issue with setting up the classpaths inconsistently and I
don't see why you'd produce a GenModel...

Hi,

I agree that generating xcore and genmodel was not appropriate.

My problem is that I have an old generated editor from ecore (hightly tweaked!). When I try to load a resource, it will fail if it's an xcore but succeed if it's an ecore. Since all our new developments are done using xcore, I thought I could generate the corresponding ecore and load it as a resource in my old editor. But this created the problems I posted above.

So after your reply, I started playing a lot trying to load an xcore resource into a generated editor and found a strange issue. I created another topic for it: http://www.eclipse.org/forums/index.php/m/1102991/#msg_1102991

If I manage loading an xcore as a resource in the editor, it would solve all my problems Smile
