I don't know what to tell you - the build works fine. It's something about your environment that is not correct and I can't troubleshoot that for you.

Would it help that i used the github desktop to download the repo?

Make sure your build.properties file is in the correct directory (eg C:\Users\admin\Documents\Github\Equivalent-Exchange-3\build.properties).

Check your build.properties - that's where the build script checks to find the version of Minecraft you are attempting to build for

Shouldn't it work?

File:

#Sat Dec 28 00:14:08 EST 2013
minecraft_version=1.6.4
forge_version=9.11.1.964
mod_version=0.1

I don't know what you've done - but the build works fine. Re-setup everything I guess

Still no success. Re-downloaded and everything.
