How can I use Jenkins in MS VSTS to build Pull Requests? - jenkins

I tried to connect my Jenkins server to VSTS repo by following this Link.
https://blogs.msdn.microsoft.com/devops/2017/04/25/vsts-visual-studio-team-services-integration-with-jenkins/
However, the options are different from the tutorial.
There is no way to set a rule for Pull Request, which is what I am trying to do.
I set a new build definition to make the Jenkins build work on every commit, but doesn't work for Pull Request.

To queue Jenkins job for VSTS pull request build validation, you can follow below steps:
Create a job in Jenkins
First, you need to create a job in Jenkins. If you have already create, then skip this step.
Create and configure build definition for PR build validation
Seems you already created a build definition named Jenkins, then add
Jenkins Queue Job task.
If you didn’t configure your Jenkins as an endpoint in your VSTS project, you can click New button to specify server URL, username and password to login the Jenkins.
Then specify the Jenkins job for queuing.
Note: If your Jenkins setup as a local server (the url as http://localhost:8080), then you need to queue VSTS build by private agent which also located in the same machine.
Add build policy as the target branch policy
In the build policy, you can set the Trigger as Automatic, the Policy requirement as Required, and the Build expiration is Immediately.
Now when pull request is created or updated for merging into the target branch, VSTS build will be triggered immediately, and the Jenkins job will also be queued during VSTS build.

How to trigger jenkins job that execute automation test scripts when code is pushed in development server?

I am new to Jenkins. I have development code repository at bitbucket and another test script code repository at bitbucket. Now I have setup a Jenkins job by linking test code repository. Is there any way to trigger a build when code is pushed in develop repo?
I tried many times by pushing change in develop repo, but it does not triggers the jenkins job.
You can configure the Jenkins trigger as an SCM poll.
You will have to enter a cron expression for the polling time period, like:
*/5 * * * *
This means polling from 5 to 5 minutes. If any change is detected, then the build is triggered.
You can add the BitBucket Plugin to your Jenkins instance. It will allow you to configure a webhook in BitBucket that will then trigger any Jenkins job listening for that webhook. The plugin's page has a detailed breakdown, but the basics are;
In your repo in BitBucket, create a new Webhook using your Jenkins' url. I believe the url is generally http://[your jenkins url]/bitbucket-hook/
Make the trigger a repo push.
In your Jenkins job, check the box "Build when a change is pushed to BitBucket" under the Build Triggers section.
Now any time you commit to the repo you created the Webhook on, that Jenkins job will be run.
You can also limit what branches trigger commits by parameterizing your Jenkins build to ignore certain branches / keywords / etc if that's something you need for your specific project.
You can use webhooks to trigger build automatically. There are few options how to use it. See the following articles: this, this and this.

jenkins how can I trigger builds when there is a change on gitlab

I am trying that Jenkins build my project when there is a change in my GitLab repository. I checked the option
Build when a change is pushed to GitLab. GitLab CI Service URL: http://172.172.10.21:8090/project/myproject/myproject_frontend
and the suboptions
Push Events
Merge Request Events
Rebuild open Merge Request
Comments
Comment for triggering a build
Also I checked
Check repository (SCM) ((without schedules))
It does not work like this.
what is missing??
thanks in advance
From the look of it, you are already using Gitlab Plugin for Jenkins, you just need to :
go to your Gitlab repository, go to the "Integrations" section of the repo settings :
Then, set the webhook URL as : https://<jenkins-host>:<port>/project/<your job> :
This way Gitlab will perform a POST request on your Jenkins Job each time the selected trigger will occur which will trigger your job task if you have configured the specified event to trigger the build.

Trigger jenkins build on tfs pull request

How do i get TFS to trigger a jenkins build when a pull request is created? it would be a smoketest, to make sure everything works before merging with main.
You can use Team Foundation Server plugin for Jenkins. Integrate TFS as a git repository.
check the checkbox next to Enable Push Trigger for all jobs in the Jenkins global configuration

Jenkins integrate with BitBucket(Mercurial) doesn't pull all cahnges

I have configure my Jenkins profile with BitBucket (Mercurial). Please see the configuration.
On Jenkins profile, changes displays correctly as per bitbucket check-in history.
Jenkins build confirms the success on new builds.
But, on Jenkins server work-space folder I don't see all changes that are supposed to be part of those check-ins
Wondering why is it sometimes missing to pull some changes part of check-in history.
You actually need to configure Bitbucket hook service (Project Settings).
This way, Bitbucket will notify your Jenkins server each repository changes on the targeted branch.

Jenkins github pull request builder do not trigger downstream projects

I recently set up github pull request builder on jenkins and it works well when I commented the trigger phrase on the PR. But when I tried to run multiple jobs by setting the downstream upstream relationship, I met this problem which is jenkins triggered the job job A set up by pull request builder as normal, but wouldn't trigger the downstream job job B when job A has finished.
Here are some of settings:
In job A: just everything on the instruction page of the github pull request builder
In job B: Under Build Triggers section, I checked Build after other projects are built and set the projects to watch to be job A, and checked Trigger only if build is stable (Nothing about github pull request builder on job B)
Try doing this from the upstream project, instead. From the upstream project configuration, Add post-build action --> Build other projects, then enter the name of the project to build.
