Jenkins 多分支管道 git 配置错误

Question

I've got a multi branch pipeline in jenkins, and when I was setting it up, I cancelled the initial scan of the gitlab branches job by hitting the red cross icon.

From that point on, I cannot get it to work properly.

I've pasted the error in below.

Here's the things I've tried to fix it.

1. Restarted the software safely through the GUI
2. Restarted the container
3. Removed any folders in workspace folder on master and slave, connected with the git repository
4. Searched both machines for any files ending in *.lock, nothing relevant found
5. Created a new multibranch pipeline and used the same git repo, failed the same way.
6. Created a new multibranch pipeline and used a different git repo but from the same server using the same credentials, worked.

I'm running out of ideas

It's like there is something cached on the jenkins side for this particular git repo.

Does anyone have any further suggestions for things I could try?

Thanks in advance

Answer 1

Had the same problem:

1. Go to $JENKINS_HOME/caches (on windows it is probably C:\\Program Files (x86)\\Jenkins\\caches) - You will find a few caches, each has .git/config file
2. Read the .git/config until you find the one whose [remote "origin"] points to the git URL of the broken pipeline.
3. Remove (or better, rename) this cahce's .git/config & .git/config.lock

Worked for me.

Answer 2

Deleting the workspace fixed mine
