title: How override loglevel from application.conf in sbt tests?
body: <p>I have sbt project with test here <code>application.conf</code> which is used in <strong>tests</strong> :</p>
  
  <pre><code>akka {
      loglevel=DEBUG
      #other settings
  }
  </code></pre>
  
  <p>When I try to run <code>sbt clean test -Dakka.loglevel=INFO</code> I see debug statements in log. For example:</p>
  
  <pre><code>[DEBUG] [11/26/2014 11:47:44.328] [unit-test-akka.actor.default-dispatcher-3] [akka://unit-test/system/cluster/heartbeatReceiver] started  (akka.cluster.ClusterHeartbeatReceiver@11ee5ffb)
  </code></pre>
  
  <p>Is it possible to pass java options from command line to override settings in <code>application.conf</code>?</p>
