I just tried this myself and had some complications so I thought I would share what ended up working for me:

1. Download and install Mac OSX version of Java SE Development Kit 7
2. Under Eclipse -> Preferences -> Java -> Installed JREs, click Add, select Mac OS X VM, then click Next.
3. Enter "/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home" as the JRE home directory, enter something reasonable like "Java SE 7" as the JRE name, and then click Finish. (Note that you won't be able to navigate to the "../Contents/Home" folder. You will have to type it in manually.)
4. After adding the new JRE to the list of Eclipse installed JREs, check the box next to the new JRE that you just added and then click OK.
5. Now under Eclipse -> Preferences -> Java -> Compiler, select 1.7 from the "Compiler compliance level" dropdown and click Ok.

Hope this helps someone who has problems figuring this out. The confusing part for me was selecting the JRE home directory in Eclipse, since I wasn't able to navigate to it.
