Hi,
I defined a DSL and it works nice in the Eclipse environment (both Juno and Kepler). I use the latest xtext (2.4).
I create a main that launch the workflow to generate the infrastructure as documented in many places. It just takes arguments and pass it to the workflow:

Mwe2Launcher.main(launchArgs.toArray(new String[0]));

The workflow register the Xbase path:

Workflow {
    bean = StandaloneSetup {
    	scanClassPath = true
    	platformUri = "${runtimeProject}/.."

    	registerGeneratedEPackage = "org.eclipse.xtext.xbase.XbasePackage"
    	registerGenModelFile = "platform:/resource/org.eclipse.xtext.xbase/model/Xbase.genmodel"
    }

Unfortunately, when I export it as runnable jar file, I get the following error:

250  [main] ERROR mf.mwe2.launch.runtime.Mwe2Launcher  - Problems instantiating module my.dsl.language.GenerateMyDsl: java.lang.reflect.InvocationTargetException
