Gradlew setupDecompWorkspace error

I attempted to setup gradle using this tutorial:

When changing cd to my forge src folder (Forge 1.7.2 latest src) and then typing gradlew setupDecompWorkspace I receive this error:

I tried running it as admin because of the permission denied thing but I received the same error.
