Cannot use readMavenPom in Jenkinsfile
<p>I am working on a Jenkinsfile for use with Jenkins 2.0.  The <code>readMavenPom</code> method is not recognized.  Is there some configuration I am missing to make this available?</p>

<p>My Jenkinsfile:</p>

<pre class="lang-groovy prettyprint-override"><code>node {
  stage 'Checkout'
  checkout scm
  env.PATH = "${tool 'maven-3'}/bin:${env.PATH}"
  stage 'Build'
  def pom = readMavenPom file: 'pom.xml'
  echo "${pom}"
  sh "mvn -DskipTests=true verify"
}
</code></pre>

<p>When run, I get the following error:</p>

<blockquote>
<pre><code>java.lang.NoSuchMethodError: No such DSL method 'readMavenPom' found among
