title: How do I find out Apache Buildr/Maven 2 repo names
body: <p>I'm just starting to use Apache Buildr and I'm constantly running into the problem of not knowing what repo urls and versions are available for me to use.</p>
  
  <p>For example I want to use Scala 2.8 in a build file, the id i previously used was:</p>
  
  <pre><code>2.8.0-SNAPSHOT
  </code></pre>
  
  <p>But now this is not found. I also want to use the latest version of Apache POI. If I look on the maven2 repo:</p>
  
  <pre><code>http://mirrors.ibiblio.org/maven2/
  </code></pre>
  
  <p>I can see that it only has up to version 3.2.</p>
  
  <p>Is there any standard way of finding repos and searching them for what they have available?</p>
