Jenkins DSL multibranch pipeline github push trigger

Question

I am using the jenkins dsl plugin multibranchpipeline job(https://jenkinsci.github.io/job-dsl-plugin/#path/multibranchPipelineJob) to create a multi branch pipeline. I have created jenkinsfile which handles the build jobs for each branches. I couldnt figure out how the github push trigger can be enabled through pipeline as code. All the examples I could find are using the jenkins web UI or the pollscm option. Can someone please help on how this can be enabled through code.

Answer 1

Project was hosted in github.In jenkins dsl multibranchpipeline, i was using the git branchsource at first. Then push events were not triggering builds. After i started using github branchsource, push events were automatically generating builds.

ie.

multibranchPipelineJob('example') {
branchSources {
    git {
        id('12121212') // IMPORTANT: use a constant and unique identifier
        remote('https://github.com/jenkinsci/job-dsl-plugin.git')
        credentialsId('github-ci')
        includes('JENKINS-*')
    }
}
}

Was changed to

multibranchPipelineJob('example') {
branchSources {
    github {
        id('23232323') // IMPORTANT: use a constant and unique identifier
        scanCredentialsId('github-ci')
        repoOwner('OwnerName')
        repository('job-dsl-plugin')
    }
}
}
