Using JDO 3.0 with App Engine and Gradle - google-app-engine

Question

I am trying to migrate to JDO 3.0 in a cloud endpoint Framework 2.0 and Guice environment. I am using the datanucleus Eclipse plugin.
I checked the following documentation:
Using JDO 3.0 with App Engine
There is only a Ant or Maven docu. In my Gradle env, when starting the appengine standard server in eclipse, i get the error appended below.
Does anyone have a hint? Maybe the copytarget not set in Gradle build script correctly?
