Jenkins can not clone Git repository over Git/SSH on Windows

Question

I have successfully cloned Git repository in Jenkins over Git/SSH on Windows 2008 32-bit. When I tried to do the same on Windows 2008 64-bit, Console Output page gets stuck here:

Démarré par l'utilisateur anonymous
Checkout:book / C:\Jenkins\workspace\book - hudson.remoting.LocalChannel@1da691a

Checkout:book / C:\Jenkins\workspace\book - hudson.remoting.LocalChannel@1da691a
Cloning the remote Git repository
Cloning repository origin

When I stop the build (after a few minutes of being stuck there), I get the rest of the error message:

• I can clone the repository via Git read-only URL git://github.com/zeljkofilipin/watirbook.git from Jenkins on both machines
• I can clone via Git/SSH URL [email protected]:zeljkofilipin/watirbook.git from the command line on both machines
• I can clone via Git/SSH URL from Jenkins on 32-bit machine, but not on 64-bit machine.

The only difference I can notice between the two machines (not counting that one is a virtual machine on my laptop, and another is a real machine in Switzerland) is that the first one is 32-bit and the second one is 64-bit.

Not sure if that could be related, but 32-bit machine has location set to Croatia, and 64-bit machine to Switzerland (as you can see from Git output in French).

I've gone through these pains recently. Especially frustrating is the lack of error logs in this scenario: probably because MSysgit prompts user on the console when trying to recover - which doesn't get through Jenkins console.

Based on my experience here are a few key elements to watch for:

1. a mix of both Msysgit and Cygwin installed: MSysgit worked better for me- but I assume you're using that too
2. some people have more luck with <MSYSGIT_ROOT>\cmd\git.cmd than <MSYSGIT_ROOT>\bin\git.exe
3. making sure your slave runs as the same user (which is not the default upon service-based installs).. - oh I see you got that too
4. setting HOME variable for windows slaves explicity
5. basically make sure the same .ssh keys are reached when under Jenkins.
6. for debugging, I found it useful to create a test job with no SCM, but run git clone in an "Execute shell/batch" build step. That should reveal a bit more info. BTW, you can do an env in the same step and maybe ls %HOME%/.ssh

I think the above is what gave me a working a Windows 7 64bit Jenkins slave with git support - although I thought this had more to do with some other fine config detail than with 64 vs 32 bits. Good luck anyhow!
