title: Javadoc: How to make it cross-link the dependencies (Maven project)
body: <p>I would like to generate Javadoc which would include the classes of project's dependencies.
  For example, project Windup would reference JBoss Forge, TinkerPop Frames and Rewrite.</p>
  
  <p>Can Javadoc do it? How?</p>
  
  <p>If I define the G:A:V -> Javadoc URL, it should be technically doable.</p>
  
  <p>I found about <a href="http://docs.oracle.com/javase/7/docs/technotes/tools/solaris/javadoc.html#linkoffline" rel="nofollow"><code>javadoc -link</code></a>.</p>
  
  <p>I have also found Maven's <a href="http://maven.apache.org/plugins/maven-javadoc-plugin/aggregate-jar-mojo.html" rel="nofollow"><code>&lt;detectLinks&gt;</code></a> but setting it to <code>true</code> made no change.</p>
  
  <p>I've experimentally tried:</p>
  
  <pre><code>&lt;additionalparam&gt;-link http://docs.jboss.org/forge/javadoc/2.13.0-SNAPSHOT/&lt;/additionalparam&gt;
  </code></pre>
  
  <p>And that works.
  However, I'd like to make Maven do this link resolving. Just as the <code>detectLinks</code> is supposed to do.</p>
