Jenkins Multibranch Config: How to Filter branches based on variable string?

if you want to use the wildcard you can provide like below:

In this example it will discover only qa and dev branch.

NOTE: You have to use "Discover branches" also with "filter by name (with wildcards)" behaviour.

Rather than filtering with wildcards, you could try filtering branches with regular expression. In our case, pattern like:

(master|develop|release.*|feature.*|bugfix.*)

has been working well to cover the repository. That is, assuming that you follow Git Flow or similar methodology. Unfortunately, there is no simple way to sync the configuration between MultiBranch Pipelines build from one repository. Neither Multibranch Pipeline, nor Organization plugins are designed to work with Multiple Jenkinsfiles.

Also, you can try to sync only the branch configuration between Projects using Jenkins script console. Most of the Job configuration does not have to be set on Project level. For instance, you can create shared script (or shared library) to would be sourced by other jobs, to set the same job properties on each of them.
