title: Migrate a report created with Makefile into a Maven site report
body: <p>I am quite new to maven but asked to move my current report which is created by a Makefile in a subdirectory via <code>make all</code> into a <code>mvn site</code> report.</p>
  
  <p>I put all my non-java stuff for my report into a <code>legacy-report</code> directory. So the current tree looks roughly like this:</p>
  
  <pre><code>pom.xml
  legacy-report/
      Makefile
      www/           # &lt;&lt;&lt; created by 'make all'
         index.html 
  subtree-1/
      pom.xml
      src/
  subtree-2/
      pom.xml
      src/
  </code></pre>
  
  <p>So my questions to enable <code>mvn site</code> for my legary-report are</p>
  
  <ul>
  <li>What maven (reporting) plugin should I use?</li>
  <li>How should I change the directory layout?</li>
  <li>How do I integrate that into the main <code>pom.xml</code>?</li>
  <li>Do I need a <code>pom.xml</code> in my <code>legacy-reporting</code> dir, what does it look like (roughly)?</li>
  </ul>
