Jenkins multibranch pipeline Scan without execution

Question

Is it possible to Scan a Multibranch Pipeline to detect the branches with a Jenkinsfile, but without the pipeline execution?

My projects have different branches and I don't want that all the children pipelines branches with a Jenkinsfile to start to execute when I launch a build scan from the parent pipeline multibranch.

Answer 1

In your Branch Sources section you can add a Property named Suppress automatic SCM triggering.

This prevents Jenkins from building everything with an Jenkinsfile.

Answer 2

Also, you can do it programatically

import jenkins.branch.* import jenkins.model.Jenkins   for (f in Jenkins.instance.getAllItems(jenkins.branch.MultiBranchProject.class)) {   if (f.parent instanceof jenkins.branch.OrganizationFolder) {     continue;   }   for (s in f.sources) {     def prop = new jenkins.branch.NoTriggerBranchProperty();     def propList = [prop] as jenkins.branch.BranchProperty[];     def strategy = new jenkins.branch.DefaultBranchPropertyStrategy(propList);     s.setStrategy(strategy);   }    f.computation.run() } 

This is a Groovy snippet you can execute in Jenkins, it's gonna do the scanning but will not start new "builds" for all discovered branches.
