Eclipse still using java 6 as jre on Mac OSX

Question

I have installed Eclipse SDK 3.7.1 on my mac, which is running mac osx 10.8.4. I am trying to get eclipse to use java 7, which is installed to /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/ But when I view eclipse's installation details it's still using to my old java 6 installation. Even after adding -vm /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/bin/java to the eclipse.ini file.

Also edited the Info.plist file to point to java 7

Anyone have any suggestions here? I'm completely out of ideas.

Please note: I am a newbie with macs. Any suggestions, big or small would be greatly appreciated :)

If you're trying to get the VM that eclipse runs under to change then it's the Info.plist you need to modify, and it should be changed in the section that says how to specify the different VMs. In my case I changed it to run with the 1.6 VM using:

<string>-vm</string><string>/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java</string> 

in the eclipse array of the plist.

if you want to force a specific 1.7 VM, you use:

<string>-vm</string><string>/Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/bin/java</string>

Note, this is not the eclipse.ini, this is the Eclipse.app/Contents/Info.plist. This is because of the slightly different way that the Mac launches eclipse from other platforms
