Git problem with Linux master and Windows slave

[jdtangney]

My Windows slave can't find git. All other slaves (Linux) work correctly.

The slave is Windows 7 with Cygwin installed, running Cygwin sshd and git. The master connects to the slave via ssh and I am able to run bash commands using "execute shell" build step, like this:

[JDT] $ sh -xe C:\Users\jenkins\hudson5633305261937738873.sh

winbuild01\cyg_server
+ echo /home/jenkins
/home/jenkins
+ /usr/bin/git --version
git version 1.7.9
+ echo /bin/bash
/bin/bash
Finished: SUCCESS

The master is Jenkins 1.503 with Git plugin 1.1.19

But when I run a job that tries to clone a git repo, I get this:

It can't find /usr/bin/git? Maybe the git plugin makes assumptions about the environment? Maybe it's assuming a windows-like file system, rather than the Cygwin rooted file system? Here's the slave log:

Is it just a matter of forcing the git plugin to recognize the Cygwin layout?

I would be most grateful for any help with this!

Is there a reason you're running a Git plugin version that is a year old?

I don't know if it will help, but it seems like you're more likely to get a response if you install the latest Git plugin (1.4.0).

Unfortunately, based on what I saw in your mail message and my lack of experience with the Git plugin in a cygwin environment, I don't have any other suggestions.

Hi,

 

[sorry for top posting]

 

1)      Execute shell assumes Unix, so it works fine in cygwin.

2)      Your cloning happens in the Windows world (not in cygwin), it doesn’t know what /usr/bin is.

 

Try removing git from cygwin and install msysgit instead (integrates better into the Windows world and works from cygwin, too). If you have a git installation defined in your global Jenkins config, either remove it completely or remove absolute paths from it (use only “git” instead of “/path/to/git”). You can also omit “.exe”, so that this definition will work in both worlds.

 

HTH...
