How to make Jenkins build something on pushing to GitHub?

[Yuri Kanivetsky]

Hi,

I have a pipeline job. It has "GitHub project" checked in settings. Project url is specified. And "GitHub hook trigger for GITScm polling" is checked in Build Triggers. I can see notifications coming from GitHub in System Log:

Mar 21, 2017 7:23:28 PM INFO org.jenkinsci.plugins.github.webhook.subscriber.DefaultPushGHEventSubscriber onEvent

Received PushEvent for https://github.com/user/prj from 10.0.3.1 ⇒ http://jenkins.rademade.com:8080/github-webhook/

Mar 21, 2017 7:23:28 PM INFO org.jenkinsci.plugins.github_branch_source.PushGHEventSubscriber onEvent

Received PUSH for https://github.com/user/prj from 10.0.3.1 ⇒ http://jenkins.rademade.com:8080/github-webhook/

The job has hello world pipeline. Jenkins master node is running in lxc container, if anything. And doesn't have slave nodes. But when I click "Build Now" it sort of builds. I'm running Jenkins 2.32.3. Also, I fixed Jenkins complaining about being run behind proxy, or something along those lines.

How do I make it build when pushing to GitHub repository? What do I check?

Project url matches what's in the log, except for trailing slash. But when I try to remove it, it reappears.

Regards,

Yuri

Your job need to have a scm configuration for it to be triggered on commits.  Either configure it as Multibranch Pipeline job or add a "git" or checkout step in your normal pipeline.

Can you elaborate on 'add a "git" or checkout step in your normal pipeline' part? I tried it with this pipeline:

node {

    git credentialsId: 'b22c8273-0293-8364-2463-233ab3898fe', url: 'g...@github.com:USER/REPO.git'

    echo 'Hello World'

}

I can see notification from GitHub coming in Jenkins' System Log, but build doesn't get triggered.

In the pipeline I created I checked "GitHub project", filled in the "Project url" text field (e.g., https://github.com/rails/rails), and checked "GitHub hook trigger for GITScm polling".

Just in case, relevant Stack Overflow question: http://stackoverflow.com/questions/42897125/how-do-i-make-jenkins-do-anything-on-git-commit/42968421

Hello Yuri,

Am in an identical situation. Were you able to nail this issue?

Hi,

Yep, I switched to Multibranch pipeline. You can find my "report" here: https://stackoverflow.com/a/42968421/52499 But I haven't finished setting up Jenkins. But at least it now starts the build when new commits come.
