Hi

I think something changed in the last release of the platform. If I have
an Xcore metamodel which ¨refers¨ to an Xtext metamodel then when a
clean is performed, this line of code appears in the *PackageImpl.:

import ecore.EcorePackage;

Has anyone encountered this problem? At the moemnt the solution is to
not use the generated metamodel from XText and to split the
functionality into one Xcore project with my metamodel and a separate
Xtext editor for the my Xcore metamodel.

Hmmm.  Like a version of Ecore where the GenPackage doesn't have the
basePackage properly set.

No, but there are definitely issues with how Xtext persists their
models as well as their tendency to put them in the src folder
rather than in the models folder.

Please open a bugzilla with a simple test case that I can use to
reproduce the problem.  In general there are problems with models
that contain cross project references which are fixed the following
bugzilla which is awaiting review:

There are also issues with Xtext's GenModels and Ecore models
containing absolute platform:/resource references where they
"should" contain relative references so they can be properly
resolved to other installed bundles...
