I made some progress, adding the xcore.ui plugin (and its dependencies) reads the xcore files into a Resource. This
works mostly except for references across xcore files. The files are in the same directory, but the references are not
resolved it seems.
I only read one of the files in a resource (using resourceSet.createResource(..)), I expected the other file to be read
also when the references are resolved.
Should I somehow setup/configure the resourceset?
I attached the xcore files I use for testing.

Hi Ed,
Indeed that was the problem, I now make sure that the project is refreshed before I run the headless build. This seems
to help. Also the project has a xtext nature set that helps to.

Hi Ed,
Still struggling with xtext getting to identify other xcore files in the same project. I have tried different uris to
load the xcore resource (through a resourceset), for example:
/org.eclipse.emf.texo.modelgenerator.test/src/org/eclipse/emf/texo/modelgenerator/test/models/samples/sport-competition.xcore
where the first segment is the project name.
To give some context, I start a launch config which runs headless and then programmatically generates files based on
models read through resources. I can get to the IProject and other things. I also tried refreshing the dev project
programmatically before I load the resource (to hope that xtext would 'fire' on a refresh).
Is there a way that I can 'force' xtext to scan a certain directory/folder/project? Where does xtext store all the
resolved xcores/types?

It generally does that for any project with an Xtext nature.

Good question. I'm not sure. Somewhere in the workspace's .metadata...

Hi Ed,
Thanks, I am still struggling with that references between xcore files are not resolved when I read the xcore files in a
ResourceSetImpl. I even make sure that the xcore files are all read in the same resourceset. Also the xcore resource
contains contents with an XPackage and EPackage etc. Only the references between xcore files are not resolved.
I use platform uri's and I see that the resourceset has a resource with a uri like this:
platform:/resource/org.eclipse.emf.texo.modelgenerator.test/src/org/eclipse/emf/texo/modelgenerator/test/models/samples/sport-society.xcore
This seems to be all fine, but the resourceset also has a resource with this uri:
platform:/resource/org.eclipse.emf.ecore/model/Ecore.xcore'
and this resource has an error:
org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: java.io.FileNotFoundException:
/model/Ecore.xcore
The error in the xcore file is this:
XtextLinkingDiagnostic: null:5 Couldn't resolve reference to GenBase 'Society'.
This although the XClass Society is present in a XCoreresource in the same ResourceSet.
So I must still be doing something wrong but have no clue...

It always seems problematic to keep them in a src folder because the
generator generates references to them in the plugin.xml and that src
folder won't exist in the binary plugin...

That's a synthetic resource created on the fly. It doesn't really
physically exist...

When you're running the tests, is there really a workspace with those
resources in it?

Maybe it's good to have a look at the Xcore unit tests and how/why they
work...
You might want to use our setup tool to setup the Xcore environment for
that purpose: https://wiki.eclipse.org/Setup-Eclipse
