triggering pipeline job with github changes - jenkins

I want to configure a cicd pipeline in jenkins, with every change in github the job has to be triggered automatically. I configured freestyle job and iam able to trigger my freestyle job with every push in the Github. When iam trying the same with my pipeline job it is not getting triggered.below is the configuration of pipeline job
and my pipeline code is simple to test with below code.I ran it once and twice to take effect. after that also for any change in my github my pipeline is not getting triggered automatically.
node {
stage('test') {
echo "test"
}}
Could anyone let me know why my pipeline job is not able to automatically trigger with github changes when my freestyle job is able to trigger? What am i missing in my pipeline job?
I also added the below configuration as suggested but still no luck. Inspite of all the configuration for automatic triggering what am i missing here.

You need change job type to pipeline.
Inside you repository put Jenkinsfile and adjust hook.

Webhook trigger for jenkins remotefile multibranch pipeline job

I have a multibranch configuration job, which I have created for using the remote jenkins file plugin, I have git repo in which I have the "jenkinsfile" named as customjenkins Now I am trying to configure the job in such a way that when ever a change is done to the "jenkinfile" the build should trigger, but in my case the top build is only triggered but the job with repo inside doesnt trigger and only can be done manually, please see the picture below for better understanding. Can anyone tell me what am I missing here

Continuous deployment branch wise using Spinnaker

I'm using Jenkins multibranch pipeline for CI process and for CD using Spinnaker.
I've gone through almost all documents, support channels etc. from spinnaker for "how to create spinnaker multibranch pipeline similarly as jenkins" but didn't find anywhere.
After integrating jenkins to spinnaker, in drop down list of jenkins jobs in spinnaker pipeline configuration, it shows all multibranch jobs separately. Hence for each branch I'd need to go to spinnaker and create pipeline manually.
To solve this, I'm thinking this solution: while running jenkins multibranch pipeline job > create spinnaker pipeline(if not exist) using spin cli with required parameters(branch, version, trigger using jenkins of this running branch job etc) > and trigger the same created spinnaker pipeline after jenkins job executed.
Please advise if there is any other better way to accomplish this.
Thanks.
I am not super familiar with the multibranch plugin, but you can make this simpler by doing [ triggers ] -> [ pipeline stage calling the same pipeline ] rather than calling the entire pipeline via the spin-cli.
Alternatively, if the list of jobs generated is small or well known, you could just update the list of triggers for the same pipeline programmatically as part of your release process.
i.e, in your jenkins job
add this job to list of triggers
run rest of jenkins job
job finishes, spinnaker pipeline triggers

How to get the Generic Webhook Trigger Plugin to work with multibranch pipelines in Jenkins?

I'm trying to set up a scenario where a pull request is created on github that triggers a Jenkins multibranch pipeline, and where that multibranch pipeline uses the Generic Webhook Plugin to extract values from the POST request sent from github to jenkins to be used in the script.
Unfortunately, as described on the Generic Webhook Trigger Plugin wiki:
Note: When configuring from pipeline, that pipeline needs to run once, to apply the plugin trigger config, and after that this plugin will be able to trigger the job. This is how Jenkins works, not something implemented in this plugin. You can avoid this by using Job DSL and have Job DSL create pipeline jobs with the plugin configured in that DSL.
This would be OK using a normal pipeline since it would just be a one off on creation of the Jenkins job. The problem however is that a multibranch pipeline will create a new job whenever a new branch/PR is created, and that means that for each pull request I create on github (which triggers my multibranch pipeline script), I have to then run it twice to get the generic webhook functionality working. Having to resubmit for each PR would be tedious for long-run projects.
It seems to me like there are two possible approaches to solving/improving on this problem. One is to try and play around with DSL Jobs (as suggested by the wiki); but I tried this and couldn't get it to work (it was adding a huge amount of complexity to the set up, so I've abandoned it for now).
The second possible solution is as follows: when a PR is created in github, the Generic Webhook will cause a new job to be created in the multibranch pipeline corresponding to that PR; the first time the multibranch pipeline runs the first build of this newly created job will fail for the reason given in the quote above; but then a solution might involve testing that the first job failed and somehow telling Jenkins to try rebuilding for that job again.
So my question relates to this second approach: how can I most neatly run a rebuild for this multibranch pipeline upon the creation of a PR on github?
Any advice/suggestions would be appreciated!
For triggering multibranch pipline by webhook you can use this plugin:
"Multibranch Scan Webhook Trigger"
https://plugins.jenkins.io/multibranch-scan-webhook-trigger/
Actually that is not true for multibranch pipelines. Just ordinary pipelines needs to run twice.
I updated the docs like:
When configuring from pipeline (not multibranch pipeline)...

Triggerig Jenkins pipeline job after code pushed to github

I want to know how we can setup a jenkins pipeline job which gets triggered after each commit made github private repository.
I am able to do it using a freestyle job but not able to do it using a pipeline.
I did setup the gihub project url, GitHub hook trigger for GITScm polling and wrote a simple pipeline script of checking out the branch.
When I do a changes in the branch and commit it the build wont get triggered.
Can I get a solution on this please?
It works when we add a timestamp block in the pipeline code.
I m able to trigger the pipeline by Adding a GitHub Webhook in Jenkins Pipeline.
I have followed steps mentioned in this blog.
In my case jenkins is running on localhost. Replacing localhost with your jenkins_url should work.
Also, I did not found GitHub Pull Requests mentioned in the blog, so I skipped that step.
After completing the configuration you have to build the pipeline manually once, after that everytime a developer commits a code to GitHub, pipeline build will be triggered.

Trigger Jenkins Multibranch Pipeline Scan from another job

Is it possible to trigger Scan Multibranch Pipeline Now action for a Jenkins Multibranch Pipeline from another Job? I have certain issues integrating my old version of Gitlab with Pipeline Jobs in Jenkins and came upon such a workaround.
Alternatively, would it be possible to trigger Scan Multibranch Pipeline Now with a notifyCommit web hook?
The purpose of this would be to Scan Multibranch Pipeline whenever a change occurs in the Git repo, so that new branches are detected after such a change.
Another purpose, which I am unable to achieve otherwise (except for periodic polling per branch which is plain evil to me), is to trigger build of branches affected by given changeset. I use old GitLab (7.8) which does not work with the ordinary Gitlab plugin and the Gitlab Hook plugin does not work with pipeline jobs, so my workaround would be to have an non-Pipeline Job to be triggered by Gitlab Hook plugin and this job would in turn trigger Scan Multibranch Pipeline.
Turned out that simple notifyCommit web hook did the job
