Configure git properties

Create jobs as functions

https://github.com/hereischen/hola-jenkins/blob/b12cc7a41e683294498256a356230b6ff422de10/dsl/seed.groovy

def createDeploymentJob(jobName, repoUrl) {
    pipelineJob(jobName) {
        definition {
            cpsScm {
                scm {
                    git {
                        remote {
                            url(repoUrl)
                        }
                        branches('master')
                        extensions {
                            cleanBeforeCheckout()
                        }
                    }
                }
                scriptPath("jobs/deploy.groovy")
            }
        }
    }
}
        
createDeploymentJob(deployName, repoUrl)
queue(deployName)

Git SCM properties

    branchSources {
      github {
        apiUri(GITHUB_API_URI)

        scanCredentialsId("37477e0c-2ab6-46fe-a83b-64b1add4777d")
        checkoutCredentialsId("37477e0c-2ab6-46fe-a83b-64b1add4777d")
        repoOwner(GITHUB_ORGANIZATION_NAME)
        repository(repositoryName)
        buildForkPRHead(true)
        buildForkPRMerge(false)
        buildOriginBranch(false)
        buildOriginBranchWithPR(false)
        buildOriginPRHead(true)
        buildOriginPRMerge(false)
      }
    }

Run a script

Method 1:

        configure {
            // my Jenkinsfile doesn't exist in the chef Cookbooks for 900 repositories... 
            // how can we set a seperate git repo for shared scripts? we don't want to use submodules
            it / factory(class: 'org.jenkinsci.plugins.workflow.multibranch.WorkflowBranchProjectFactory') {
                owner(class: 'org.jenkinsci.plugins.workflow.multibranch.WorkflowMultiBranchProject', reference: '../..')
                scriptPath("jenkinsfile")
            }
        }

Method 2:

    factory {
        workflowBranchProjectFactory {
        // Relative location within the checkout of your Pipeline script.
        scriptPath('jenkinsfile')
        }
    }

Branch discovery trait

    configure {
        def traitBlock = it / 'sources' / 'data' / 'jenkins.branch.BranchSource' / 'source' / 'traits'

        traitBlock << 'jenkins.plugins.git.traits.BranchDiscoveryTrait' {}
    }

Generating folders for jobs

Another way to add git SCM's using clojures

This might be useful for advanceed properties? https://github.com/sumeetraheja/seed-jobs/blob/5698c6f1a3d66586d3454355126bc84a43fcfb64/jobs/checkout/checkout_backend_api_tests_job.groovy

    branchSources {
        configure { node ->
          node / sources(class: 'jenkins.branch.MultiBranchProject$BranchSourceList') / data / 'jenkins.branch.BranchSource' / source(class: 'jenkins.plugins.git.GitSCMSource') {
            remote 'ssh://[email protected]:2222/checkout/checkout-api-tests.git'
            credentialsId 'jenkins-ci'
            includes '*'
            excludes ''
            ignoreOnPushNotifications 'false'
            id ''
            traits {
              'jenkins.plugins.git.traits.BranchDiscoveryTrait'()
              'jenkins.plugins.git.traits.CloneOptionTrait' () {
                extension(class: 'hudson.plugins.git.extensions.impl.CloneOption') {
                  shallow 'false'
                  noTags 'false'
                  reference ''
                  depth '0'
                  honorRefspec 'false'
                }
              }
            }
          }
        }
    }

Very interesting seeder, possibly using multiple SCMS using folder libraries?

Very interesting seeder example 2

Interesting jobs generator using DSL outside and generating workflow pipelines inside
