Please use the TypeReference(packageName, className) [message #1745995]

Hi everyone,
When I try to launch the generation of Xtext artifacts I get the following error:

[ERROR]: GeneratorException: (Element: -UNKNOWN-; Reported by: XtextGenerator)
	 java.lang.IllegalArgumentException: Cannot determine the package name of 'GS.GSPackage'. Please use the TypeReference(packageName, className) constructor

Could someone explain to me please the cause of this error.
Also i dont understand why in my manifest file the serializer plug-in is missing. Is that related to my previous error.

thanks in advance
Best regards

Xtext cannot handle your naming convestions. please create a bug at https://github.com/eclipse/xtext-core

as i said: please file a bug so that this can be fixed. t

he implementation of

org.eclipse.xtext.xtext.generator.model.TypeReference.getPackageName(String, boolean)

expects the emf package to stick to java naming conventions

a.b.c.XyzPackage
