  <p>maven compiler version is something like this:</p>
  
  <pre><code>&lt;plugin&gt;
      &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
      &lt;artifactId&gt;maven-compiler-plugin&lt;/artifactId&gt;
      &lt;version&gt;2.3.2&lt;/version&gt;
      &lt;configuration&gt;
          &lt;source&gt;1.6&lt;/source&gt;
          &lt;target&gt;1.6&lt;/target&gt;
          &lt;encoding&gt;${project.build.sourceEncoding}&lt;/encoding&gt;
          &lt;showDeprecation&gt;true&lt;/showDeprecation&gt;
      &lt;/configuration&gt;
  &lt;/plugin&gt;
  </code></pre>
