[2.6.3 to 2.7.1] Using eclipse application is broken [message #1420736]

Hello!

I've upgraded from Xtext 2.6.3 to 2.7.1. When I try to edit my dsl files in a normal eclipse application, I get errors like this:

An internal error occurred during: "XtextReconcilerJob".
java.lang.IllegalStateException: Unresolved proxy http://]<my grammar>/Idl#//include_decl. Make sure the EPackage has been registered.

include_decl is an import statement, but the error occurs with every grammar rule, as far as i could try.

With 2.6.3 everything was fine. I haved used a fresh workspace.

Are there any steps i missed while upgrading to the new Xtext version?

Regards
Gerriet

Hi,

does not seem to be update related.
are you sure the epackage registration is contained in a plugin.xml (with correct path) and you dont have any warnings on build.properties?

maybe there is a plugin.xml_gen that has to be merged to plugin,xml

Thank you for your response!

I've investigated my plugin.xml and found that there was a wrong URI indeed. It was a left over from a rename refactoring a few weeks ago. Somehow! with 2.6.3 it does not made any problems?

But now i get the following error when generating from my dsl:

Seems that there are dependency problems. My eclipse is a current Luna release.

In version 2.7.1 the missing class seems to be renamed to

org.eclipse.xtext.xbase.scoping.batch.ImplicitlyImportedFeatures

Do I need to update something?
