What Operating System are you using (both controller, and any agents involved in the problem)?

Mac OS X - 12.4

Reproduction steps

Turn on Git support in the Plastic SCM server
Add a new multibranch Jenkins job for a specific repo
Let it scan the logs or trigger a scan manually -- this works as long as there's only one branch (/main)
Now create a second branch in your repo (I created a sub-branch, don't know if the error happens also with top-level branches)
Run the multibranch job again

It now crashes with

ERROR: [Sun Jul 24 18:41:38 EEST 2022] Could not fetch branches from source XXX
[Sun Jul 24 18:41:38 EEST 2022] Finished branch indexing. Indexing took 0,14 sec
FATAL: Failed to recompute children of JobName
hudson.plugins.git.GitException: Command "/usr/bin/git fetch --tags --force --progress --prune -- origin +refs/heads/*:refs/remotes/origin/*" returned status code 128:
stdout: 
stderr: fetch-pack: protocol error: bad band #65
fatal: protocol error: bad pack header

Expected Results

Multibranch jobs should work when there are multiple branches

Actual Results

Multibranch jobs stop working when there's branches other than /main in the repo. I think that this is probably an issue in the server itself and not the Jenkins plugin but I am reporting it here also.

The error message is:

ERROR: [Sun Jul 24 18:41:38 EEST 2022] Could not fetch branches from source XXX

Anything else?

Here's the Branch Sources setup for the multibranch job (with login information redacted):

UPDATE: This seems to start happening at random even when only one branch is involved, as I have another repo without any branches (other than /main) and the same error happens there. It works for a few hours until the aforementioned error starts to happen.

Hi @Tommigun1980,

Unfortunately you're having issues with the GitServer feature in a Plastic SCM server, interacting with the Git plugin for Jenkins. The scope of this repo only includes the Plastic plugin for Jenkins, not the GitServer features of the Plastic SCM server nor interactions with other Jenkins plugins. You can report Plastic SCM issues at support@plasticscm.com.

I'm closing this issue, sorry for the inconvenience.

jenkinsci / plasticscm-plugin
