Hello

Xtext version 2.12.0

When I try to create a maven xtext project that uses a xcore model I get the following error:

591  [org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher.main()] ERROR textGeneratorResourceSetInitializer  - Couldn't initialize Xcore support. Is it on the classpath?
594  [org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher.main()] ERROR textGeneratorResourceSetInitializer  - Could not load XcoreLang.xcore.
