could anyone help?

after updating to xtext 2.1 from 2.0 i get the following exception when running the mwe workflow for my language

Looks OK on first sight. Do you have a plugin dependency to org.eclipse.xtext.xbase?

Need professional support for Xtext, EMF, Eclipse IDE?

Hi Gary,

please make sure that you register the generated EPackage for Xbase in
the standalone setup of your workflow.

Sebastian

And how exactly do I do this?

Simply add this line to the StandaloneSetup section:

registerGeneratedEPackage = "org.eclipse.xtext.xbase.XbasePackage"

Thanks! The MWE2 workflow now runs flawlessly, but ...

I get two dozens of Java and Xtend errors (see attachment).

I am working with your (otherwise unmodified) domain model tutorial material in <git://github.com/szarnekow/Xtext-Workshop-Development-Workspace.git> as of 2011-07-05. Does it have any incompatibilities wrt Xtext 2.1?

many thanks for the various suggestions! I have been able to eliminate the previous error by carry out the following steps

1. updating the explicit version numbers asccociated with the xtext imports in the MANIFEST.MF file

2. adding registerGeneratedEPackage = "org.eclipse.xtext.xbase.XbasePackage"

however I still have a problem, I now get the following exception while building with mwe

Also as a comment I have read about mwe in the documentation. However, I am still not sure what options and fragments I need in the mwe file. Whats more is there an overall document of what the available fragments are?

one again may thanks for any help

As for your direct problem: https://bugs.eclipse.org/bugs/show_bug.cgi?id=362655
You can use this as a workaround: https://github.com/dslmeinte/LessCss/blob/master/nl.dslmeinte.xtext.css/src/nl/dslmeinte/xtext/CorrectedSimpleNamesFragment.java

The correct URL for CorrectedSimpleNamesFragment is https://github.com/dslmeinte/LessCss/blob/c72ffb6d2a66703ad5001847e8ba83342856c791/nl.dslmeinte.xtext.css/src/nl/dslmeinte/xtext/css/CorrectedSimpleNamesFragment.java

but it doesn't work with Xtext 2.0 Sad

Even when I enable it in my mwe2 instead of

fragment = exporting.SimpleNamesFragment {}

I still get the same error as before:
