Two things.

The first is I don't use sudo on Linux, as it's usually just me on the 
box. As such, I've used "su -s /bin/sh -c..." instead.

The second is are you sure you want /home/teamjenkins/workspace/Squeak? 
And not:

/var/lib/jenkins/workspace/Squeak

A symbolic link from one to the other gives an appearance of things but 
not a permission of things.

Actually, I did it in that dir and got the same response:

[root at server1 Squeak]# pwd
/var/lib/jenkins/workspace/Squeak
[root at server1 Squeak]# su -s /bin/sh -c "git reset --hard" - jenkins
fatal: Not a git repository (or any of the parent directories): .git


I'm back in front of the computer now, so I can respond more quickly.
