title: Unable to compile using Java 1.7 in Jetbrains Intellij after moving from 1.6 to 1.7 (maven based project)
body: <p>Using Jetbrains 11.2 project based on a Maven project. Then I required to move to 1.7. I have 1.7 installed , I updated my pom.xml and I can rebuild the whole package using maven okay.</p>
  
  <p>I've modified every setting I can see in Intelli Projects settings regarding Java version </p>
  
  <ul>
  <li>Project SDk </li>
  <li>Project language Level</li>
  <li>Modules Languages/Sources/Language Level</li>
  <li>Modules Languages/Dependencies/Module SDK</li>
  </ul>
  
  <p>but I cannot get it to compile a file it complains:</p>
  
  <pre><code>Error:javac target release of 1.6 conflicts with source release 1.7
  </code></pre>
  
  <p>I then tried on my other dev machine using the same codebase but a different Intellij Project and on this I get a similar error:</p>
  
  <pre><code>Error:javac: source release 1.7 requires target release 1.7
  </code></pre>
  
  <p>I cannot see anything else to change in order to get this working.</p>
