title: Eclipse: javac: target release 1.6 conflicts with default source release 1.7
body: <p>I am trying to perform a build on Eclipse Kepler but when I do so I get the following error   <code>javac: target release 1.6 conflicts with default source release 1.7</code></p>
  
  <p>I have changed the Java Compiler to use 1.6 but this warned me that the default JRE was 1.7. I then went to Installed JREs removed 1.7 and created a new one for 1.6.</p>
  
  <p>This still gives the sames error. I also saw something about adding -vm and the java path to eclipse.ini but this didnt help either.</p>
  
  <p>Does anyone know what to do?</p>
