using GIT plugin: cannot clone submodule

[Emil Petkov]

Hello,

I have set up Jenkins and installed the GIT plugin (https://wiki.jenkins-ci.org/display/JENKINS/Git+Plugin).

1. First, I created a depot of my repository by executing:

git clone --bare /home/git_repos/admin_pci.git /home/jenkins_bare_repos/admin_pci.git

2. Added the clone as the remote origin for the original so I can push to the clone:

cd /home/git_repos/admin_pci.git

git remote add origin /home/jenkins_bare_repos/admin_pci.git

3. Then created a job in Jenkins: selected GIT for "Source Code Management", Repository URL = /home/jenkins_bare_repos/admin_pci.git, "Branches to Build" = 'master', etc

4. Ran the job and got the following error:

It seems that the submodule of the project cannot be cloned correctly. Is this a well known issue with GIT submodules? Any ideas how to resolve it?

Thanks in advance.

submodule indeed are only redirections to external repo and - as such - still point to the canonical git repository, even you created a local clone. I don't know any workaround but get access to the target repo.

I do have access to the target repo where the GIT submodule is. It's just that it asks for a password since it is shared repo accessible to developers via SSH. Seems the GIT plugin breaks on trying to clone the gitsubmodule since it has no way of knowing the SSH password, basically the GIT plugin hangs.

Any ideas whether this is supported as part of the GIT plugin somehow?

Thanks

I would use passwordless SSH keys to access the submodule, in that case.

Indeed,

I've plan to integrate git-plugin with ssh-credentials plugin so it gets more flexible, but have no better workaround for short term

Is it a good idea then to not use the GIT plugin and instead clone the project and update the submodule in a Jenkins build step directly?

Thanks

THis is exactly what I did to circumvent the problem, I will work without the GIT plugin until the SSH credentials are better integrated.
