Jenkins Scan Multibranch Pipeline stopped detecting develop branch

Question

I am using an organization folder in Jenkins to discover all repositories that contain a Jenkinsfile.

It had been working fine until recently. At some point, the develop branch of one of the repositories was removed. That branch does exist and contains a valid Jenkinsfile.

When I rescan the project the log shows how it examines the branch but says nothing about finding or not finding the Jenkinsfile:

Looking up myorg/myrepo for branches
Checking branch develop from myorg/myrepo
Checking branch master from myorg/myrepo
      ‘Jenkinsfile’ found
    Met criteria
...

What could be the problem here? Any advice about how to troubleshoot this?

I've tried the usual solutions: delete the branch, create new ones that are detected without any problem, recreate the develop branch...

Answer 1

Obvious check, but still, worth a check :

• Typo in Jenkinsfile name in dev branch
  • Try a pull request from master (that seems to works) to dev branch
• Scan filter in Folder setup updated ?
• JenkinsFile syntax could be wrong ? (not sure if it can impact, but you might have a look if something changed in dev lately)
• dev branch visibility constrain ?

Hope this helps Regards
