Hi

Some versions of Acceleo were broken by an EMF change.

What version of Acceleo are you using?

Regards

Hi

Acceleo 3.7.0 is two years and seven releases earlier than 3.7.7 for 2018-12. However since it precedes the 3.7.6/3.7.7 troubles, I would expect it to work.

You never provided more detail than "Could not initialize class org.eclipse.papyrus.infra.emf.internal.resource.CrossReferenceIndex" so it isvery hard to help you.

Class initialization failure is almost always the tip of the iceberg, so you need to tunnel down the stack trace to find the actual cause.

But you didn't provide the stack trace.
