To get a specific branch of the android source, you use the repo just like you would to get the latest version. After you follow the instructions on the info for setting up the machine in the links that were supplied by the other answers, you would run

repo init -u https://android.googlesource.com/platform/manifest -b cupcake 

That will pull the 1.5 version of the source code.

I'd imagine you would get it from the android git repository?
Web interface: https://android.googlesource.com/
SDK: http://developer.android.com/sdk/index.html

Details on how to access it:

Note, the repository contains the current version so the above is likely uninteresting to you.
I found this though:
