I want to import the Xtext Grammar EMF model via

	referencedResource = "http://www.eclipse.org/2008/Xtext"

in my MWE2 workflow
Running the workflow yields the error genmodel not found.

How can I work around this problem?

wonder what the goal of this is.

you can try referencedResource = "platform:/resource/org.eclipse.xtext/org/eclipse/xtext/Xtext.genmodel"
or referencedResource = "classpath:/org/eclipse/xtext/Xtext.genmodel"
or "classpath:/org/eclipse/xtext/Xtext.xtext"
or something like that

Thank you very much the first option did it.
Can you explain why the genmodel of Xtext is not registered with its URI ?

HI

A GenModel has no Epaxkage so it cannot possibly be registered by its non-existent nsURI.

It is however consistently registered by the following plugin.xml snippet.

  <extension point="org.eclipse.emf.ecore.generated_package">
    <package 
       uri = "http://www.eclipse.org/2008/Xtext" 
       class = "org.eclipse.xtext.XtextPackage"
       genModel = "org/eclipse/xtext/Xtext.genmodel" /> 
  </extension>

that populates a Map accessible by EcorePlugin.getEPackageNsURIToGenModelLocationMap().

Regards

Ed Willink
