graphx VertexRDD java.lang.ClassNotFoundException

I am developing a SparkJob on jobserver (v0.6.2 spark 1.6.1) using spark graphx and I am running into the following exception when trying to launch my job on Spark JobServer:

  }

Altough I've included graphx dependency in my build.sbt and in Dependecy.scala on jobserver.

Any Help?
