Hello world,

yesterday I have downloaded Eclipse Kepler (Version: Kepler Release
Build id: 20130614-0229) and I followed the instructions to install Xtext via the update function. An it seems to be fine.

Now I have tried to run the 5 Minute Tutorial from the website - and I get the failure below.

Has anyone an idea to help me out. This would be nice.

hmm looks like https://bugs.eclipse.org/bugs/show_bug.cgi?id=370196
did you try to use a full eclipse from http://www.eclipse.org/Xtext/download.html

yes, and it work. But its not from eclipse.org its from itemis and it is a Juno. But this is enough for me and what I have to do...

I agree with you I think it could be the bug, maybe...

Thanks for your prompt answer.
