Hi Richard
You can run an mwe2 file from maven (using the fornax plug-in), as you
can see here:
https://github.com/LorenzoBettini/xsemantics/blob/master/plugins/it.xsemantics.dsl/src/it/xsemantics/dsl/GenerateXsemanticsModel.mwe2
Note that this also uses de.itemis.xcore2java.XcoreReader originally
written by Christian (you can find that in the sources of the above
project).
hope this helps
Lorenzo
