Trigger Jenkins Job from Bitbucket on Pull Request - jenkins

Hoping to gather insight from professionals. My end goal is to trigger a jenkins build whenever a bitbucket pull request happens. If anyone could give me an ELI5(explain like I am 5) answer it would be greatly appreciated. Sorry if this is the wrong format, I am new to jenkins and stackoverflow.
What I have done so far:
Created webhook in bitbucket and gave the url to my jenkins job. example: http://jenkinsURL:8080/job/boulevard-dev/generic-webhook-trigger/invoke?token=myPull_Request_Token
Pull request webhook trigger
In Jenkins, under source code management I have: Source Code Management Settings. This is currently fetching a ton of branches, failing, then building the master branch when the job starts?
For build triggers, other stackoverflow articles have pointed me to the "Generic Webhook Trigger". https://github.com/jenkinsci/generic-webhook-trigger-plugin
I am not entirely sure how this generic webhook trigger should effectively be setup? Hoping someone has experience using it and could explain what is needed.
This is what have seen referenced in other articles.Build Triggers settings Build triggers settings 2
Questions:
What does a correct setup / example of the generic webhook trigger look like?
Currently, my job triggers when a change is made to master or merged to master, how can I specify to my job that I want the bitbucket pull request branch to be built?
Also, I found this, not sure if its related to my issue or not? https://jira.atlassian.com/browse/BCLOUD-5814

As per your requirement, you can trigger a Jenkins build whenever a bitbucket pull request happens by following the below steps, in my case, it's working fine.
Step(1) - Configure Jenkins
(i) Add your bitBucket repo and branch to source code management
(ii) On build Triggers setup Poll SCM to * * * * * for run every minute to check pull request from bitBucket.
Step(2) - configure Bit Bucket Hook
(i) Go to settings and add a new hook, now setup pull request trigger as per your requirement.
Step(3) - Make a pull request and see the new job automatically triggered on Jenkins.

Trigger Tekton pipeline from Bitbucket webhook

In one of our project we have to integrate Bitbucket webhook with Tekton pipeline that means whenever developer commits any changes to Bitbucket repository, Tekton pipeline is triggered and will perform several steps to build.
Earlier we have used GitHub webhook with Tekton and it was working fine.
For Bitbucket webhook, we are getting below error:
failed to replace JSONPath value for param pusher-name: $(body.actor.name): name is not found".
I checked the payload coming from Bitbucket webhook and found there is no such field name.
I used bitbucket-push cluster trigger binding plugin.
Can anyone help us to resolve this issue?
You can use tekton triggers and event listener for that.
With BitBucket, the author name should be somewhere in the actor.username, actor.display_name or actor.nickname
Here's a sample bitbucket push payload
You may have other errors. Switching from one git provider to another, you may have to re-do your interceptors, triggertemplates, ...
Meanwhile, it's unclear what you refer to, by "I used butbucket-push cluster trigger ...". Where did you find this? Checking Tekton Triggers samples, there's no author.name. Sounds like your issue relates to GitHub-specific configurations.

Jenkins GitHub Webhook not triggering builds

I have a Jenkins server (2.249) setup and I have connected my GitHub account and tested the connection and it works fine, but for a normal pipeline job where you enter the GitHub repo url, Jenkins seems to add an extra slash at the end? So I can't get my normal pipeline job to build on a push event, I've checked the logs and it says:
skipped [repo-name] because it doesn't have a matching repository.
So I've starting to think its because Jenkins is adding an extra slash at the end of my repo url? The webhook on the GitHub side works as it gives back a green tick and it works on another multibranch job for push events, just not the normal pipeline jobs.
Don't know if the problem is still on after more than one year but because I've just faced the same issue, here is an answer that help me to understand : https://serverfault.com/a/884717
Just to resume the answer : you have to complete the git part (scm) of your Project Configuration :
For my part: as the project is a private one, in an organisation that I can't update to add a personal token (as I'm not the owner of the resource - organisation), I choose to use the git+ssh url with a ssh key access to this repo. The next trick for github is to add the github's IPs to the jenkins user know_hosts file !
The reason behind the need to add twice the repository url is obscure. But I could only see that in https://github.com/jenkinsci/github-plugin/blob/master/src/main/java/com/cloudbees/jenkins/GitHubRepositoryNameContributor.java#L113 the method parseAssociatedNames will try to get the Jenkins'job associated names from :
com.cloudbees.jenkins.GitHubRepositoryNameContributor$FromSCM
com.cloudbees.jenkins.GitHubTrigger$GitHubRepositoryNameContributorImpl
org.jenkinsci.plugins.github_branch_source.GitHubSCMSourceRepositoryNameContributor
I think the third one is for multibranch pipelines. I don't really know for the second but indeed the first one is fromSCM configuration !

Trigger Jenkins Pipeline on Pull Request

I have a Github personal account. I have configured Jenkins to trigger build on the PUSH event. I want to do the same on the Pull Request event and later for new branch event. How to handle this?
This article can help you to trigger build when code pushed in Github.

I used this for mine projects too
Hope this can help you

Build Jenkins project on BitBucket pushes and pull requests

I have a scenario where I'm setting up Jenkins for my app. I have BitBucket set up and firing appropriate webhooks.
I want to start a build whenever a push is made to the repo as well as whenever someone creates/updates a pull request.
I've looked at the BitBucket Plugin. It works good if I have the BitBucket webhook to fire for all pushes.
Then I added the BitBucket Pull request plugin to build on every pull request create/update. So I changed the BitBucket webhook preferences to fire on pushes and PR creates/updates.
Unfortunately, these plugins have conflicting settings, hence they cannot be used at the same time (as per my research, the minute I send custom webhooks from BitBucket, the first one stops working, but the second one works)
Has anyone been able to set this up correctly? Maybe there's a plugin for what I want, but I couldn't find it.
I want to keep writing a proxy in front of Jenkins to manage webhooks the last option, only if there really is nothing I can do.
Thanks for the help!

How to trigger a Jenkins job from a status change in Jira

I have been looking for a while now for a way to trigger a Jenkins job from the status or a ticket/story in Jira changing status. To give a more detailed example when my team moves a ticket to the 'ready for test' column we would like to be able to trigger a sanity test pack in Jenkins, the ideal situation would then be that we are able to post the results (generated as a html) as a comment on the ticket within Jira. Failing that we would like to be able to publish the results as simply pass/fail.
I have recently been looking at the Jenkins Jira plugin but this does not seem to have the functionality to work both ways, in other words it can post results after a job has run but you cannot trigger the job from a change of status in Jira. Is there any such plugin available or is it something that we will need to create ourselves?
Cheers in advance
So, basicly there are webhooks in jira (https://developer.atlassian.com/jiradev/jira-architecture/webhooks). With it you can configure it to trigger specific url on issue status change. The specific url should be jenkins API, for example for triggering a build you should call an external url like (if you are building with parameters): http://server/job/myjob/buildWithParameters?token=TOKEN&PARAMETER=Value
Some more info https://wiki.jenkins-ci.org/display/JENKINS/Remote+access+API
I have written a Jenkins plugin that supports JIRA status change trigger: jira-trigger-plugin.
This plugin also injects an environment variable of JIRA_ISSUE_KEY, so you can utilise this information to publish your result back to JIRA e.g. using REST API.
Please follow as mentioned below:
GIT:
You can set the web hooks for git/ bitbucket /stash on commit which inturn should change the state of task in JIRA.
JIRA:
Once you in JIRA. define the workflow for your task.
In this particular workflow you can set a post-function where the web hook should be configured. In this configuration of webhook in events define JQL as below:
status CHANGED FROM "To Do" TO "ready to test".
In the same mention the job that needs to be fired in the URL section.
You can look through webhooks in Jira :
https://support.atlassian.com/jira-cloud-administration/docs/manage-webhooks/
You also need to add the Generic Webhook Trigger plugin to your Jenkins :
https://plugins.jenkins.io/generic-webhook-trigger/
You can find here an example on how to use the Generic Webhook Trigger plugin with Bitbucket Github and Gitlab. https://github.com/jenkinsci/generic-webhook-trigger-plugin/tree/master/src/test/resources/org/jenkinsci/plugins/gwt/bdd
It involved multiple steps
If you are using Git/Stash/BitBucket (which i implemented),
You can simply
configure the commit hooks in your Stash/Bitbucket
Attach events to your JIRA workflow
Jenkins JOB - post build events - configure Notify
Stash plugin Set the Poll SCM
That's it
