Jenkins Github Organization job type not discovering Jenkinsfile in `master`

[dkowis]

Issue

Impacted version: 4.23.0

• jenkins: 2.107.1
• github-branch-source: 2.3.3
• github-api: 1.90

Deployment mode: Standalone war file

Problem description:

I'm pretty confident this used to work, but I haven't been able to play with my jenkins/gitbucket setup at home in a while. The problem I'm seeing is that jenkins is no longer picking up the master branch to do builds on. It's not selecting the branch to do work.

Finished examining dkowis/monopolytracker

There's only one branch, and it's got a Jenkinsfile, so it should be selected to build, but it appears that it's somehow unable to find that Jenkinsfile, and so is not building anything at all.

It will pick up pull requests, and other branches and build those, but it doesn't seem to do it until after the scan happens. I'm not sure if the pull request payload changed, but I don't think that's it. There's no errors in the log from Jenkins.

Also of note, deleting and creating a new organization from scratch, and jenkins picks up no branches to do work in.

I guess it caused by the bug in Contents API (#1943). It has been already fixed in #1940 and going to be released in tye next version of GitBucket (4.24.0 or 4.23.1).

I can confirm that this is due to the bug described in #1943. We have the same behavior in our Jenkins. So this will thankfully be fixed soon

Since this bug affects a lot of users, I will make a maintenance release 4.23.1 as soon as possible.

GitBucket 4.23.1 is out!

This issue seems to have resurfaced again when I upgraded from 4.28 to 4.30, it used to find the jenkinsfile on all my branches when using the GitHub Multi-branch pipeline in Jenkins, now it doesn't find it on any giving the following message:

  Getting remote branches...

    Checking branch master
      ‘Jenkinsfile’ not found
    Does not meet criteria

    Checking branch develop
      ‘Jenkinsfile’ not found
    Does not meet criteria

There doesn't seem to be any errors on Jenkins or in the logs from GitBucket. This issue has made all my Jenkins multi branch git hub projects think that the branches no longer need to be built so nothing with build when using this method anymore (as it can't find any Jenkinsfile to build off). My guess is somewhere in the Gitbucket GitHub API it's not returning the files correctly, but thats as far as my knowledge goes XD
