Jenkins hangs at git fetch

Question

I'm a beginner with Jenkins and I'm trying to get it to run some unit tests in my.NET project.

When I run a build it hangs when trying to fetch from the Git repository.

ERROR: Timeout after 10 minutes
 > C:\Program Files\Git\cmd\git.exe config --local --remove-section credential # timeout=10
ERROR: Error fetching remote repo 'origin'
hudson.plugins.git.GitException: Failed to fetch from https://github.com/name.of.repo

I've generated the known hosts and copied the .ssh dir to C:\Windows\SysWOW64\config\systemprofile.ssh as per the jenkins instructions at https://wiki.jenkins-ci.org/display/JENKINS/Git+Plugin under "Jenkins, GIT plugin and Windows"

I ran ssh [email protected] from the command line and I can successfully authenticate.

What can I try next?

Answer 1

This is probably a firewall issue. You can authenticate to Github using SSH (port 22), so that route is working. Your job however is trying to access github via https://github.com (port 443) which timeouts. Try accessing github over ssh by changing the repository url to [email protected]:account/repository.git (you can find this URL on the main page of the repo, dropdown 'Choose a clone URL', option 'SSH'.

Answer 2

I had the same problem as the OP. SSH credentials are stored in Jenkins and work for many other nodes accessing the same repo. I can ssh into the machine as the Jenkins user and do a git clone on the repo using the same SSH repo URL as the Jenkins job ([email protected]:account/repo.git).

As a workaround, I set the git credentials in the Jenkins job to none for now. I assume that allows it to use the credentials stored locally.

It is working now.
