title: Maven builds on file changes
body: <p>Is there anything already out there that would help with either / both of following?</p>
  
  <ul>
  <li>Perform a Maven install when a file within that module changes</li>
  <li>Perform a Maven install on the module <em>and its dependencies <strong>if</strong> they have changed</em></li>
  </ul>
  
  <p>I'm pretty sure I've heard of a Maven option to build dependencies as well but struggling to find anything from Googling...</p>
  
  <p>Perhaps this isn't going to be Maven specific but instead involve a file watching tool that is OS specific, if so I would be interested in hearing about tools for Windows (XP).</p>
