git plugin for Jenkins fails to clone a repo from local machine. Error code 128

It's been a while since this question was asked, but I had this problem today and there are very few resources. Most probably, because people tend to connect to git repositories remotely.

I checked using strace what exactly jenkins was doing and yes, it was a problem with permissions.

But I solved it in a simpler way than answer #2 - by adding jenkins to the git server group - in my case, git1: root# gpasswd -a jenkins git1 root# service jenkins restart

When installing Jenkins as a service, by default, Jenkins does not create a user directory as in: /home/jenkins. Jenkins default home directory is set to /var/lib/jenkins. From my work-around, as you would expect, jenkins has trouble accessing local resources from other users directory.

I moved my cloned repo under Jenkins default home directory i.e. under /var/lib/jenkins so my Repository URLin Jenkins Project configuration looks like: file:///${JENKINS_HOME}/repo/<myprojectname>

UPDATE: The above works fine ...but I found a better way to do it from this blog

The steps are outlined here:

look up /etc/init.d/jenkins script. There are a few $JENKINS variables defined . This should lead you to the sysconfig for jenkins i.e. /etc/sysconfig/jenkins. Stop your jenkins instance:

sudo /sbin/service jenkins stop

Take a backup

cp /etc/sysconfig/jenkins /etc/sysconfig/jenkins.bak

In this file, change the following property:

$JENKINS_USER="<your desired user>"

Change ownership of all related Jenkins directories:

chown -R <your desired user>:<your user group> /var/lib/jenkins

chown -R <your desired user>:<your user group> /var/cache/jenkins

chown -R <your desired user>:<your user group> /var/log/jenkins

Restart jenkins and that error should disappear

sudo /sbin/service jenkins start

This error should go away now!
