Using base Ecore types in .xcore file

[podcherklife]

Is there a way to do something like this:

class Mapping {
  refers EAttribute[1] fromAttribute;
  refers EAttribute[1] toAttribute;
  refers EClass[1] mapperClass;
}

I can create EClasses like these in ecore gui editor(or in emfatic, though I suppose its not a part of emf project), but I cant find a way to make this work with xcore.

What I want is to write some java codegen against classes/interfaces generated from these xcore definitions. I suppose I could m2m some dsl-ish xcore model to ecore and then generated java apis from that, but may be there is jsut a straighforward way of using those types directly.

Yes you can do that like this:

I attached a zip.

org.example.xcore.zip

Be sure to create an Xcore project so that it has the nature and build in the .project file.

Oh dear, I forgot that I need to migrate this off the wiki before it shuts down:

https://wiki.eclipse.org/Xcore

Ahh, it works indeed, its exactly the missing nature that was stopping eclipse from generating proper types, even though editor almost works without that nature.

I got confused by the fact that my attempt to invoke xcore codegen in maven also failed to resolve the same types so I thought it is more of a fundamental limitation. Oh well, I guess I have figure out now what else I have to set up to call that from maven programmatically without relying on full headless eclipse to do the job.

Thank you!
