Question

I have implemented a Domain Specific Language(DSL) using Xtext which contains expressions, so in order to check easily their validity I decided to use Xtext-typesystem Framework.
I was trying to implement the examples given in this tutorial, but when I use

@Inject   private ITypesystem ts;

and then try to run Launch Runtime Eclipse in order to check my rules’ validity, editor won’t open and I get many errors. Below there are some of them:

(What does Papyrus have to do with this?)

And lots lots other errors.
Any ideas about why is this happening?

Thank you in advance.

Somehow you introduced a (transitive?) dependency to the bundle org.eclipse.xtext.xbase.lib. Please make sure that you import that one in your manifest and that you don’t exclude it from your launch config. The eGit / SVN key binding conflict does not seem to be related to this.
