issue with multi branch project plugin and git authentication
Gijs kuijer
Hi all!
We are trying to set up Jenkins with the multi branch plugin. Jenkins is installed on a server together with Gitlab.
The multi branch plugin works as far as listing all the branches and trying to build then when we use HTTPS as the credentials. The part that goes wrong is listed in this question:http://stackoverflow.com/questions/32499990/jenkins-git-plugin-using-local-when-authenticating-with-https. The git plugin somehow uses a wrong option.
If we use the ssh credentials, create a ssh key with open ssh, put it in the jenkins directory in the .ssh directory with the id_rsa name and put it in Gitlab using the user we created for Jenkins we get the following error in the branch sync log:
