title: Multiple goals in maven mojo
body: <p>I am developing a mojo that I envision will have 2 goals. </p>
  
  <p>e.g. </p>
  
  <pre><code>    /**
      * @goal validate-user-config
      * @goal build-user-project
      */
  </code></pre>
  
  <p>So far I've only ever defined a single goal with the syntax above. My question is how can I create two goals and conditionally vary the behavior of the <code>execute()</code> function?</p>
