title: Maven plugin executing another plugin
body: <p>I'm trying to create a new plugin to package my latest project.  I'm trying to have this plugin depend on the maven-dependency-plugin to copy all my projects dependencies.</p>
  
  <p>I've added this dependency to my plugin's pom, but I can't get it to execute.</p>
  
  <p>I have this annotation in my plugins main Mojo:</p>
  
  <pre><code>@execute goal="org.apache.maven.plugins:maven-dependency-plugin:copy"
  </code></pre>
  
  <p>I've tried a few other names for the goal, like <em>dependency:copy</em> and just <em>copy</em> but they all end with a message saying that the required goal was not found in my plugin.  What am I doing wrong?</p>
  
  <p>Secondary to this is where to I provide configuration info for the dependency plugin?</p>
