title: Maven update dependencies in POM
body: <p>Are there any preexisting Maven plugins or commands to update the dependencies in the POM? 
  Example: (if this was in my POM)</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;dependency&gt;
      &lt;groupId&gt;commons-lang&lt;/groupId&gt;
      &lt;artifactId&gt;commons-lang&lt;/artifactId&gt;
      &lt;version&gt;2.3&lt;/version&gt;
  &lt;/dependency&gt; 
  </code></pre>
  
  <p>Is there a command or plugin I can run to get it to update the dependency to: </p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;dependency&gt;
      &lt;groupId&gt;commons-lang&lt;/groupId&gt;
      &lt;artifactId&gt;commons-lang&lt;/artifactId&gt;
      &lt;version&gt;2.4&lt;/version&gt;
  &lt;/dependency&gt; 
  </code></pre>
