Write error based on Akka code missing or invalid dependency detecte

The specific error message is as follows:

Error:scalac:missing or invalid dependency detected while loading class file ' Actorsystem.class '. Could not access term typesafe in package com,because it (or its dependencies) is missing. Check your build definition formissing or conflicting dependencies. (Re-run with '-ylog-classpath ' to see the problematic classpath.) A full rebuild could help if ' Actorsystem.class ' is compiled against an incompatible version of COM.

In fact, I have added the Akka-actor_2.10-2.3.8.jar jar package ....

The workaround for the above problem is:

1. Download this jar in Http://central.maven.org/maven2/com/typesafe/config/1.3.0/config-1.3.0.jar.

2. Add to Classpath. Can.

I'm using the Scala 2.10 version;
