How to run Eclipse with different Java version?

  • Open eclipse config file eclipse.ini in your Eclipse folder.
  • Add -vm yourPath\Java\jre6\bin\javaw.exe like:

    -startup
    plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
    --launcher.library
    plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120522-1813
    -product
    org.eclipse.epp.package.java.product
    --launcher.defaultAction
    openFile
    --launcher.XXMaxPermSize
    256M
    -vm 
    C:\Java\jre6\bin\javaw.exe
    ...
    

If the path contains spaces there is no need to escape them, see the Eclipse Wiki for more specs. The -vm option and the path must be on separate lines. The -vm option must come before the -vmargs option. On Linux, the path would typically be /bin/java instead of the Windows path shown above. You must use the Java and Eclipse versions must match (i.e. 32-bit Eclipse runs on 32-bit Java and 64-bit Eclipse runs on 64-bit Java).
