Attempting to execute the demo class as ...
java -cp build/libs/SparkSetuDemo-1.0.jar com.sunny.spark.demo.SparkDemo

results in an error having to do with the shade jar created by gradle.

The shade jar overlays all of the contents of dependent jars. This can cause similarly named dependencies to be overwritten. In this case the reference.conf file in each akka jar was overwritten. The resolution described for maven projects is here implemented for gradle using the com.github.johnrengelman.shadow plugin.
