title: Maven site (Maven 3) generates empty site folder
body: <p>I'm attempting to create a basic maven site using the maven site plugin. So I added this to my pom:</p>
  
  <pre><code>&lt;reporting&gt;
      &lt;plugins&gt;
          &lt;!--JavaDoc setup--&gt;
          &lt;plugin&gt;
              &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
              &lt;artifactId&gt;maven-javadoc-plugin&lt;/artifactId&gt;
              &lt;version&gt;2.7&lt;/version&gt;
              &lt;configuration&gt;
                  &lt;defaultAuthor&gt;Leon Blakey&lt;/defaultAuthor&gt;
                  &lt;defaultVersion&gt;${project.version}&lt;/defaultVersion&gt;
                  &lt;links&gt;
                      &lt;link&gt;http://download.oracle.com/javase/6/docs/api&lt;/link&gt;
                  &lt;/links&gt;
              &lt;/configuration&gt;
          &lt;/plugin&gt;
      &lt;/plugins&gt;
  &lt;/reporting&gt;
  </code></pre>
  
  <p>And ran <code>mvn site --errors</code> </p>

  <p>Hmm, odd that there's no output. So when I check target/site, its empty. The only folders are images/ , css/ , and WEB-INF/ , filled with some generic pictures. No javadoc and no site.</p>
  
  <p>This is reproducible with <code>mvn site:site</code> and <code>mvn org.apache.maven.plugins:maven-site-plugin:2.2:site</code> (apparently maven only wants to use 2.0.1 by default)</p>
  
  <p>Whats strange is that I can go back to maven 2.2.1 and successfully generate a site. But when I use 3.0.1-RC1 (happens to come with Netbeans), it fails. </p>
  
  <p>What am I doing wrong that would make the site plugin fail in 3.0.1 but not 2.2.1?</p>
