Unable to run robospice-sample-okhttp sample

[jaccunio]

Very strange issue, all other samples work correctly except for this one. What I did: imported robospice-sample-okhttp project as Maven project, run as Android application (these steps worked for all other robospice samples), I get the following logcat error:
