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

Jenkins is running in Docker container with image: jenkins:2.452.3-lts The host is Alma Linux.

Reproduction steps

1) Create Multibranch Pipeline 2) Configure "Scan Multibranch Pipeline Triggers" to "Periodically if not otherwise run". 3) On every scan the configuration of every branch job will be updated. More specifically the ID of the credentials used for authorization to Bitbucket 4) Combined with the config history plugin it will generate big number of files.

Expected Results

The ID of the credentials should be the same on every run.

Actual Results

Anything else?

This significantly increases Jenkins load in case Job configuration history plugin is enabled as it keeps track of all the changes.

[nfalco79]

Is this issue fixed with latest available version? The built credential id was passed as null and by documentation if null it automatically generate an id. Commit #cb6984fb6fef06b0b9c3390d1a56f728ae2283d0 changes this behaviour passing the original credentialsId so I would expect the job definition does not change. Could you confirm?
