Using JDO 3.0 with App Engine and Gradle

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?
