No "Build Triggers" option for Blue Ocean pipeline

I have researched this issue a lot and cannot find an answer to that, so I have setup a simple project on Jenkins before and I get all the perks of the "Build Triggers" tab where I can select exactly what could trigger the project build (for example pull requests).

However, in the Blue Ocean project I can only see these options under the specific branch > View Configuration, and it doesn't allow me to save any of the options configured, it just shows the configs and there is no save button. I have attached the screenshots below:

This is the Project > Configuration, it allows me to save changes and everything but has no option for build triggers. Project Configs

This is under Project > Branch (master) > View Configurations, it shows the build triggers I want but no option to apply these changes into that specific branch. Branch Configs

So, I guess the question is, how can I add the build triggers to my blue ocean pipeline?

Solution

  • The build triggered seen under a branch should be the reflection of the trigger directive made in a Jenkinsfile directive which is either:

    • cron
      Accepts a cron-style string to define a regular interval at which the pipeline should be re-triggered, for example:

        triggers { cron('H */4 * * 1-5') }

    • pollSCM
      Accepts a cron-style string to define a regular interval at which Jenkins should check for new source changes. If new changes exist, the pipeline will be re-triggered. For example:

        triggers { pollSCM('H */4 * * 1-5') }

    • upstream
      Accepts a comma separated string of jobs and a threshold.
      When any job in the string finishes with the minimum threshold, the pipeline will be re-triggered. For example:

        triggers { upstream(upstreamProjects: 'job1,job2', 
                     threshold: hudson.model.Result.SUCCESS) }

    That would be paired with a when directive, which specifies the branch

    branch
    Execute the stage when the branch being built matches the branch pattern given, for example:

    when { branch 'master' }

    Note that this only works on a multibranch Pipeline.

    Nmaresh Kulkarni adds in the comments:

    Looks like the remote trigger from script is not an option, and this option is must for folks behind a firewall.
    The only way that I can think of is to create a fake trigger job, and configure that as an upstream trigger for my actual repo with Jenkinsfile.

     curl -X POST -u "$username:$api-token" "$jenkins-url/job/$job-name/job/$branch-name/build"

    This API is handy to trigger remote builds within local network after pushing to GitHub or Azure repos.
