I have a jenkins instance which has a windows slave machine attached. I also have a job running which resides in github and I have the trigger - "Build when a change is pushed to GitHub" set.

as I push a change to github, there is no build triggered on jenkins. I check and see that the payload does get tranferred to jenkins in the "Github hook log" but I get the following error:

Caused by: java.io.IOException: Cannot run program ""C:\Program Files (x86)\Git\cmd\git.exe"": error=2, No such file or directory

Basically complains about not being able to run the command C:\Program Files (x86)\Git\cmd\git.exe" ls-remote -h https://xx/xx/xx master

But as I manually go into my slave machine and run the command, it works fine.

Please note that 1. I have made the adjustment where jenkins slave service logs in as admin so that it has all permissions. 2. My default jenkins server is a linux box and the slave machine is a windows box. Obviously both have different git executable path. So I am wondering if jenkins runs this command on my linux box for some reason.

I do have the project setup to run on the windows slave box only and that works fine as it builds fine(so it is able to find the git executable for the job)

Any pointers?

Also does anyone know how github plugin for jenkins works with slave machines(does it look for git in the slave or does it go to where jenkins resides, as that might be the source, though have no idea what the solution for that weird case would be?)
