Jenkins multibranch pipeline Scan without execution

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.

If you are using Jenkinsfiles to define your pipelines (you should be!), add the overrideIndexTriggers(false) option.

pipeline {
  options {
    overrideIndexTriggers(false) // disable branch indexing build trigger
  }

After much struggle I've found this solution, it should only avoid triggering the build when branch indexing and not disable automatic build after commit. Just add it in the first stage of your project:

when {
    not {
        expression {
            def causes = currentBuild.getBuildCauses()
            String causesClass = causes._class[0]
            return causesClass.contains('BranchIndexingCause')
        }
    }
}

organizationFolder('my-folder') {

  buildStrategies {
     buildRegularBranches()
     buildChangeRequests {
       ignoreTargetOnlyChanges true
       ignoreUntrustedChanges false
     }
   }
}

Note: plugin basic-branch-build-strategies is required

If you are using job-dsl you could simply do this and it will scan everything without actually running the build the first time you index.

organizationFolder('Some folder name') {
  buildStrategies {
    skipInitialBuildOnFirstBranchIndexing()
  }
}

To add to @Stqs's answer, you could also set noTriggerBranchProperty it using Job DSL plugin, e.g.:

multibranchPipelineJob('example') {
  ...
  branchSources {
    branchSource {
      ...
      strategy {
        defaultBranchPropertyStrategy {
          props {
            // Suppresses the normal SCM commit trigger coming from branch indexing
            noTriggerBranchProperty()
            ...
          }
        }
      }
    }
  }
  ...
}

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.

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

This prevents Jenkins from building everything with an Jenkinsfile.
