title: how to make maven release plugin skip tests?
body: <p>I'm running <code>mvn release:prepare -Darguments="-Dmaven.test.skip=true -DskipTests"</code> on the master checkout of <a href="https://github.com/spotify/docker-client" rel="noreferrer">Spotify's docker-client</a>. But I can't get maven's release plugin to skip the tests. Why doesn't maven in this case respect the CLI flags?</p>
  
  <p>I'm also curious what causes the release plugin to execute the surefire-plugin. There's no surefire-plugin specified in <code>pom.xml</code>.</p>
