            Reporter: HYG


in sbt, to run the wordcount example using the command 
"gearpump-examples-wordcount/run" will cause the classnotfound exception:

error] (run-main-0) java.lang.NoClassDefFoundError: com/typesafe/config/Config

it seems to lack the main method's augument akkaConf: Config in the command, 
however, no doc was found how to construct this augument to the  "main" method.
in addition, in previous version, like 
b5f11040b775062eb4b3143144d0316b45766054, to run this example without  akkaConf 
argument will work. 
so, i believe this should be illustrated, and i still couldn't work it out now, 
can anyone help?
