title: Change the Java version Eclipse is running under
body: <p>I want to run my Eclipse in a newer Java version (jdk 1.7) because of compatibility problems with the Window Builder Plugin</p>
  
  <p>"Eclipse is running under 1.6, but this Java project has a 1.7 Java compliance level, so will not be able to load classes from this project. Use a lower level of Java for the project, or run Eclipse using a newer Java version."</p>
  
  <p>So I suppose, I've to change the vm of Eclipse in the configurations.</p>
  
  <pre><code>-vm
  C:\Program Files (x86)\Java\jre6\bin\client\jvm.dll
  eclipse.home.location=file:/C:/Program Files (x86)/Eclipse IDE for Java EE Developers/
  eclipse.launcher=C:\Program Files (x86)\Eclipse IDE for Java EE Developers\eclipse.exe
  eclipse.launcher.name=Eclipse
  eclipse.p2.data.area=@config.dir/../p2/
  eclipse.p2.profile=epp.package.jee
  eclipse.product=org.eclipse.epp.package.jee.product
  eclipse.startTime=1351770082498
  eclipse.vm=C:\Program Files (x86)\Java\jre6\bin\client\jvm.dll
  eclipse.vmargs=-Dosgi.requiredJavaVersion=1.5
  </code></pre>
  
  <p>But I'm not realy familiar with all the statements, and my question is which ones do I've to change in order to run Eclipse with jdk 1.7?</p>
