title: Scala and Akka : ActorSystem class not found even with the config.jar
body: <p>I'm working on an Android application written in Scala in which I also use the Akka library. As I'm quite a beginner, I'm using Eclipse and I let it manage the dependencies. Currently, I have in my build path:</p>
  
  <ul>
  <li>the Scala library 2.10.2 </li>
  <li>the Android libraries</li>
  <li>akka-actor_2.10-2.2.1.jar </li>
  <li>config-1.0.0.jar</li>
  </ul>
  
  <p>But sadly, when I try to instantiate this :</p>
  
  <pre><code>val system = ActorSystem("mySystem")
  </code></pre>
  
  <p>I'm meeting this kind of error :</p>
