title: Have Java 8 for Luna and Java 7 for Juno
body: <p>I want to use both Eclipse Juno and Eclipse Luna simultaneously in my machine, for different projects.</p>
  
  <p>My machine has Java 8 installed. This works perfect with Luna since the projects I have in Luna are exclusive to Java 8.</p>
  
  <p>My projects in Juno need Java 7 strictly. It seems I have a build path issue (I guess it is because I don't have Java 7 in my system).</p>
  
  <p>I downloaded JRE 7 and tried to install it. However, it tells me that I already have Java 8 installed in my machine.</p>
  
  <p>What do I do then? How can I have Java 7 for my Juno projects?</p>
  
  <p>Mac OSX Mavericks.</p>
