  <p><strong>More info:</strong></p>
  
  <ol>
  <li>I'm using Maven version 3.0.5</li>
  <li>I cannot see the <code>maven-nar-plugin</code> in the <a href="http://repo.maven.apache.org/maven2/" rel="nofollow">Central Repository</a> either</li>
  <li>I see it is available @ <a href="http://duns.github.io/maven-snapshots/" rel="nofollow">http://duns.github.io/maven-snapshots/</a>. I don't know how to tell maven to look here. It's looking into (2) by default.</li>
