clean version doesn't create local minecraft.jar

No minecraft.jar file is downloaded

What I expected to happen was...:
I deleted the old minecraft folder and relaunched the game. I expected to find a clean minecraft.jar file in the bin folder.

What actually happened was...:
There is no bin folder and no minecraft.jar file at all even though I am still able to launch and play.

Steps to Reproduce:
1. delete current minecraft folder
2. launch minecraft to create new folder
