title: Handle different language and target levels for sources and tests with IntelliJ IDEA
body: <p>I'm interested if someone has clue how to handle this pom in projects properties of IDEA:</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;configuration&gt;
         &lt;source&gt;1.3&lt;/source&gt;
         &lt;target&gt;1.3&lt;/target&gt;
         &lt;testSource&gt;1.5&lt;/testSource&gt;
         &lt;testTarget&gt;1.5&lt;/testTarget&gt;
     &lt;/configuration&gt;
     &lt;version&gt;3.0&lt;/version&gt;
  &lt;/plugin&gt; 
  </code></pre>
  
  <p>Should I set project level 1.3 and module level 1.5 or wise verse around?</p>
  
  <p>As well anytime when IDEA reloads maven project it sets language levels as it thinks from maven to 1.3 and after always complaints about test classes. </p>
  
  <p>But this will go as bug report to JetBrains.</p>
