&gt; stacktrace
&gt; an you spot the problem? Yeah, me neither.<p>I <i>did</i> spot the problem.
But then I&#x27;m in the middle of making sbt behave civily with typescript and angular2.<p>Of course I could just use webpack or some other javascript buildtool. But I like to have integrated incremental compilation for frontend and backend. 
And since our backend is Scala I&#x27;m working in my weekends on a typescript sbt plugin. 
I guess I should get out more.
