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?)

          I tried a work around of adding the "Force polling using workspace" as an "Additional behaviour" in my git SCM definition of the windows job.

          If the poll runs on the Linux node (the master) but somehow decides it needs to use the Windows git configuration to poll the master, that might cause the Linux master to attempt to execute git from the Windows git location, instead of the Linux git location(which is what is happening in my project). That would be a bug, and I was surprised at this bug, since there are many installations of Jenkins git which use a wide mix of Linux and Windows slaves.

          I'm was not aware of such a bug, but since the "Force polling using workspace" resolved the problem for you, it may hint that is an area for more investigation.

          It does seem like github plugin bug.

          There are certainly many installations worldwide which use a wide mix of Windows and Linux computers, and which successfully poll whether or not "Force polling workspace" is set.

          You may have a configuration error in your Jenkins setup. Some things you might try as a way to test that theory:

          1. Configure a freestyle job with Git as scm from a repository accessible from all your machines (maybe https://github.com/jenkinsci/git-client-plugin.git)
          2. Configure that job to "Force polling using workspace" and configure it to poll once a minute
          3. Configure the job to limit which node can run the job, limit it to the master node
          4. Read the polling log to confirm it was successful
          5. Configure the job to limit which node can run the job, limit it to another node
          6. Wait for it to poll from that node
          7. Read the polling log to see if the polling commands are successful from that node
          8. Iterate through each of your nodes, confirming that each is able to poll with git

          If one of the nodes is discovered that it cannot poll with git, then you can review the configuration of that node, looking to see if it has incorrectly declared the location of the git program, or if it is incorrectly using the git location of the master node.

          After two weeks with no response to my observation that I'm unable to duplicate this bug, I'm closing it as "Cannot Reproduce". I run a Jenkins instance with a Linux master and several Windows slaves and do not see this problem.

          markewaite I would like to re-open this issue. We are encountering the exact same behavior, though our setup is a bit different. We are not using git hooks in our case, simple SCM Polling. As with the originally reported situation, this is happening with a Linux master an multiple (8) windows slaves. All slaves are presenting with the same issue. Setting "Force polling workspace" also works as a workaround in our case.

          We are seeing this with Jenkins 1.609.1, Git 2.4, Git client 1.16.1

          Below is our stack trace, though it does not seem to differ materially from the one in the original report:

          I should have added that we recently upgraded from an old version of jenkins where we were not seeing this behavior: Our old system was Jenkins 1.552, Git plugin 1.4 and Git Client plugin 1.6.

          I think the problem you're seeing is due to JENKINS-28943 and is resolved in git client plugin 1.18.0. I'm surprised you didn't update to git client plugin 1.18.0 at the same time you updated to git plugin 2.4.0.

          If that does not fix it, then you can also work-around the problem by changing the path to the git executable on those computers from C:\Program Files (x86)\Git\cmd\git.exe to C:\Program Files (x86)\Git\bin\git.exe
