Tycho/Maven XCore code generation [message #1722821]

Hello,

I have a project using XCore models, where the models live in different plugins and may reference each other.

I was trying to use Tycho/Maven to generate the sources, and was able to get it to work for a self-contained model using information found on this forum. However, it doesn't seem to work when a model uses model objects from another plugin.

I put together a small test-case to show the problem here:
https://github.com/hefloryd/tycho-xcore-testcase

The testcase contains two models where model.a uses a class from model.b. Code-generation works fine in the IDE. When I use maven to build, code-generation works fine for model.b, but for model.a it fails with the following error message:

[ERROR] ERROR:B cannot be resolved. (file:/P:/GitHub/tycho-xcore-testcase/model.a/model/a.xcore line : 6 column : 11)
[WARNING] WARNING:The import 'model.b.B' is never used (file:/P:/GitHub/tycho-xcore-testcase/model.a/model/a.xcore line : 3 column : null)
[ERROR] ERROR:A generic type in this context must refer to a classifier or a type parameter (file:/P:/GitHub/tycho-xcore-testcase/model.a/model/a.xcore line : 6 column : null)

This error is similar to what you would get if model.b.B was an unwrapped java type, so presumably the problem may be that the code-generation is not aware that model.b.B is a model object.

Is there any GenModel annotation that would help solve this?

Thanks,
Hans-Erik

Sorry, I'm just not familiar with how things behave in a Tycho/Maven
build. You could open a bugzilla, and maybe eventually I'll have time
to look, but that's unlikely for at least the next two months...
