title: Maven - Skip the goal execution by passing parameter
body: <p>I'm using this maven plugin:</p>
  
  <pre><code>&lt;groupId&gt;de.saumya.mojo&lt;/groupId&gt;
  &lt;artifactId&gt;gem-maven-plugin&lt;/artifactId&gt;
  </code></pre>
  
  <p>I want to be able to pass in a parameter to skip the execution of the specified goal. (e.g. <code>mvm install -skipGemPlugin=true</code>)
  How do I do that?</p>
