Git problem with Linux master and Windows slave

2013-06-06 Thread 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:

Started by user John Tangney 
[EnvInject] - Loading node environment variables.
Building remotely on win-build-slave1 
 in workspace 
c:\jenkins\workspace\JDT
[JDT] $ sh -xe C:\Users\jenkins\hudson5633305261937738873.sh
+ whoami
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:

Finding unused plugins

2013-05-29 Thread jdtangney 
Our Jenkins setup has grown rather um, "organically". We now have lots of 
plugins installed and I am sure several are not even used. Worse, we seem 
to have cases where two plugins do almost the same thing. 

How can I identify which plugins are not used by any existing job? I want 
to uninstall them.

Thanks,
