Subject Re: Eclipse import errors after akka update
Date Fri, 19 Dec 2014 05:58:54 GMT

Thanks Till for the description, I actually thought that I had the things set already what
you described since I have been working on the scala code anyways. 

It turned out that the xplugin path self updated itself by pasting my workspace path in front
of path. So when I checked if I have everything set it looked good since the beginning of
the path is same but was actually an invalid…

Sorry I missed that somehow
