title: Maven dependency issue - artifact not found in central repo
body: <p>I'm trying to build the project from this site <a href="http://www.joptimizer.com/usage.html" rel="nofollow">http://www.joptimizer.com/usage.html</a>. I downloaded the sources jar file, unpacked it and ran <code>maven package</code> in the root folder. Maven fails at the last minute saying it couldn't resolve the dependency.. </p>
  
  <pre><code>could not find artifact seventytwomiles:architecture-rules:jar:3.0.0-M1 in central repo - repo.maven.apache.org/maven2 .. 
  </code></pre>
  
  <p>I have a feeling I might need to change something in the pom.xml file for this to work, but have no idea what. Googling for this missing dependency lead me no where. In general, how would one know what to do to handle such errors (and also please help with this specific case).</p>
