`launcher rebuild` does not work with Git 1.8.3 because in line 549-551 it uses the **@** shortcut for **HEAD**. Git 1.8.3 does not know this shortcut. Using HEAD instead of @ will fix this:

```plaintext
LOCAL=$(git rev-parse HEAD)
REMOTE=$(git rev-parse @{u})
BASE=$(git merge-base HEAD @{u})

```

I think we expect people to have a newer version of Git.

Yeah, Git 1.9.x is an acceptable minimum I think.

Note I am not against fixing this provided you submit a working PR, but you got to test everything.
