1. Help > Install New Software...
2. enter the following URL into the 'Work with' field:
   

   http://build.eclipse.org/eclipse/builds/4P/siteDir/updates/4.3-P-builds

3. press 'Enter'

9. click 'Finish'
10. restart Eclipse when asked

In order to use the batch compiler only, you can follow the steps described at the link Using the batch compiler, but use the org.eclipse.jdt.core_3.9.2.v*_BETA_JAVA8.jar from your updated install.
