title: On Eclipse Mars, I can't see 1.8 in the compiler compliance level menu
body: <p>I'm using Eclipse Mars and I can't see 1.8 in the compiler compliance level menu.</p>

  <p>Prehaps, it is because I used this option to import all my plugins from my Eclipse Kepler installation. Maybe it also import preferences that causes this problem.

  <p>I added the jdk 1.8 in the Installed JREs.
  I tried to delete the .preferences folder and restart my eclipse but I still have the problem.</p>
  
  <p>Any ideas?</p>
  
  <p>EDIT : I tried to check for updates but no updates were found</p>
