Jenkins-Build when a change is pushed to GitHub option is not working

I had the same problem and solved it. The problem was that the URL had to end with a /. Meaning:

http://<jenkinsurl>:8080/github-webhook/ ✅

http://<jenkinsurl>:8080/github-webhook ❌

(Notice the missing / at the end.)

I suspect you missed the webhook url.

Besides checking the Build when a change is pushed to GitHub option, you should also add the webhook url into your Github repository to get the Auto trigger mechanism to work and here is how:

Go to your Github repository:

Settings--> Webhooks&Services-->Service--> Add Services--> Choose "Jenkins (GitHub plugin)"

Then fill in the Jenkins hook url with your jenkins url like this: http://your_jenkins_url/github-webhook/

---

And, VERY IMPORTANT, since you are installing your jenkins server in your localhost, please be aware that you shouldn't fill in above Jenkins hook url like http://localhost:8080/github-webhook/ because Github is not able to recognize localhost or 127.0.0.1 or 192.168.*.*.

Either you should use an externally accessible DNS name or an IP address, which can be recognized by Github.
