We have "stage (build)" on all our branches. Temporarily how can we skip this stage to run on all our branches in multibranch pipeline. I know one solution is use when condition on stage and ask all developers to pull that branch into their branch. But thats lot of work and coordination. Instead I am looking for a global configuration where we can simply skip the stage by name on any branch.
It sounds like you keep the Jenkinsfile alongside the code, but want to change how the Jenkinsfile runs from an administrative point of view.
You could store this stage in a separate (version control flavor of preference) repository. Before you execute the stage, load in the repository then load in the script file and within the stage execute a method defined in that file.
Alternatively, add a parameter to the build job (this assumes you aren't setting parameters via options in the Jenkinsfile) that is a boolean to use or skip the stage and you can modify the project configuration when you want to turn it on or off
