I have a question, Im trying to commit updates that im doing on my database to a Github, I am using redgate to setup the repository and commit the changes.
Anyway I am trying to connect Github repo to Jenkins, so whenever I commit change.
So the trigger is update one the repo, what I want is to get changes on the repo without pressing 'BUILD NOW' on Jenkins.
I already installed github plugin to Jenkins and but in the new version there is no trigger ' Build when a change is pushed to Github'.
Also I tried Web-hook but I am not really familiar with it.
Any hint or idea that might help!
and I will be thankful.
GitHub Jenkins Trigger
On the new release of the GitHub plugin, trigger Build when a change is pushed to GitHub has been renamed to GitHub hook trigger for GITScm polling. So choose this instead.
GitHub Webhook
There is a quick and good guide here about creating a webhook on GitHub and link it to your Jenkins build.
In short in GitHub navigate to :
Settings -> Webhooks & Services -> Service -> Add Services -> "Jenkins (GitHub plugin)"
Then
Enter your webhook URL in the “Jenkins hook URL” field and press “Add
service”
To test that everything has been configured correctly:
click on the created service and
press the “Test service” button in the upper right corner. If
everything is correctly configured, the Jenkins service has got a
green checkmark icon in the service overview and the build process has
started.
If there is no trigger for
' Build when a change is pushed to Github'.
Then simply downgrade the plugin version and try again.

Our Company used to self-host GitLab for source-code management and configured webhook on gitlab to trigger all the project pipelines on jenkins. Initially, the gitlab url was 'https://git.fulcrumdigital.com' and later for an upgraded version, they changed url to 'https://autobuild.fulcrumdigital.com'
Recently, we migrated to 'github.com' and created an organization. The source codes for various projects are found under this organization, which is private. Now, when I try to configure webhooks for these projects, I see that they deliver as intended to jenkins, but jenkins doesn't trigger the respective project's build. Instead, it gives out a message as shown below.
jenkins-github webhook error
I don't find any info regarding this webhook on global configuration page.
Here is a snapshot of jenkins logs
jenkins logs
I don't face this webhook issue for newly created pipeline-projects on jenkins. I face this issue for older pipeline-projects that already had their webhook configured earlier for gitlab.
Help me to resolve this issue and make jenkins trigger build from github webhook for older pipeline-projects.
Did you try force regenerating the webhooks?
Go to Manage Jenkins > Configure System > GitHub plugin > Advance > Re-registers hooks for all jobs.
I had this problem myself. The first thing you want to do is go to Manage Jenkins -> Configure System scroll down to the GitHub section and click on "Advanced". You will see this:
It's important to have access to your Jenkins log (I'm running Jenkins with Docker). When I clicked on Re-register hooks for all jobs, I got the following error:
In my case, the error mentioned something with my access token. So, I checked my Github personal access token and it turned out, I need to turn on Read and Write for Webhook:
Now, go back to Jenkins and click on Re-register hooks for all jobs again, and on the next push, the build was automatically triggered.
This seems to be one of the more important, but less understood and documented features of GH and Jenkins, which seems to defeat the purpose of CI entirely ...
I'm trying to setup a simple, "kick off a build when a pull request is opened" Job in Jenkins. I've scanned though dozens of posts, some several years old, but have yet to find a solution that actually works, start-to-finish. I'm using GH 2.15.4 and Jenkins 2.89.3 with the GH Pull Request Builder plug-in. I've tried setting up a pipeline job, and a freestyle project, following various "how to" posts and docs. Nothing works as expected. Not even close. I've managed to get some functionality working, but not without a lot of trial-and-error experimenting, which doesn't leave me with a warm-fuzzy in using it. Webhooks are equally worthless in accomplishing what is needed, as nothing seems to fire off a job in Jenkins, regardless of how it is configured.
For starters, are there any references or docs that explain what the following status checks are that are automatically created by Jenkins:
continuous-integration/jenkins/branch
continuous-integration/jenkins/pr-head
continuous-integration/jenkins/pr-merge
Apparently there is no way to delete or edit these ... they just "appear" courtesy of Jenkins. I've seen some discussions, but some explanations contradict one another, so they may just be outdated, inaccurate, etc. I want to know "what does what" so I know which should be 'required' as part of the PR status check.
Any pointers would be appreciated!
I agree, this problem is tricky because Jenkins and its plugins have changed so much throughout the years. Let me tell you how I accomplished what you're asking for. I will post all of my version numbers (mostly up to date).
Jenkins Version: 2.176.1 (java -jar /usr/share/jenkins/jenkins.war --version)
Plugins
github 1.29.4
github-api 1.9
github-branch-source 2.5.3
github-pullrequest 0.2.5
pipeline-github-lib 1.0
Also, I use the Blue Ocean interface, which might affect things (who knows)
blueocean 1.17.0
blueocean-git-pipeline 1.17.0
blueocean-github-pipeline 1.17.0
Github Webhooks
First off, set up webhooks for your system. This is a good guide for Github Webhooks
Go to your Github repository and click on the Settings tab. Then select 'Webhooks' in the left menu:
The URL of my Jenkins setup is https://jenkinsci.dorian.com. So, in the 'Payload URL' box, I put https://jenkinsci.dorian.com/github-webhook/
I left the settings as "application/json" and "send me everything" and "active"
The Webhooks area has a handy 'Recent Deliveries' section which can show you if your webhooks are making it to Jenkins. At first, I had the wrong URL so mine has red Xs next to them. Now, they're all green checkmarks.
Github Access Token
Many guides suggest that you provide Jenkins with a personal access token to communicate with your repo. To do that, go to your account avatar in the top right and select Settings -> Developer Settings -> Personal access tokens->Generate Token
Put whatever you want for the description. Under 'select scopes', if you just want it to work, select every checkbox in the list.
I selected:
repo:status
write:repo_hook
read:repo_hook
admin:org_hook
Click save and you'll be shown your secret key. Copy this somewhere safe (we'll use it soon).
Configuring Jenkins
Now for the hard part. Try and install all of the plugins I've listed above.
Go to Jenkins-Manage Jenkins->Configure System
Locate the Github section and click Add Github Server
Name: Github
Api URL: https://api.github.com
Manage Hooks: true
Under credentials, click "Add." You'll be brought to a menu. Select "Secret Text"
Scope: Global
Secret: paste your access token from earlier
ID: (I left this blank)
Description: DorianGithubCreds
Hit save. Then, select DorianGithubCreds from the credentials list.
To test, hit "Test Connection." Mine returns 'Credentials verified for user dnrahamim', rate limit: 4998
Now go down to Github Pull Request Builder
GitHub Server API URL: https://api.github.com
Jenkins URL override: (blank)
Shared Secret: (blank)
Credentials: DorianGithubCreds
Auto-manage webhooks: true
Everything else is blank
Configure Job
Go to the job that should be building your repo
Select 'Configure' in the left menu
Under Projects->Github Organization
Credentials: DorianGithubCreds
Owner: Dorian
Behaviors:
Discover branches
Strategy: Exclude branches that are also filed as PRs
Discover pull requests from origin
Strategy: Merging the pull request with the current target branch revision
Discover pull requests from forks
Strategy: Merging the pull request with the current target branch revision
Trust: From users with Admin or Write permission
Project Recognizers
Pipeline Jenkinsfile
Path: Jenkinsfile (my Jenkinsfile is in the project root)
Build Strategies: (intentionally blank)
Notifications
Now, when I do a pull request, or whenever I post a change to a pull request, Jenkins run a fresh build for that branch.
The Pull Request itself in Github also lists its "Status Checks" at the bottom. When the build is pending, the status check is yellow. If it succeeds it gets a green checkmark. If it fails, it gets a red X.
I initially had a problem because I had an old Jenkins box which was also configured to manage Github webhooks and build pull requests. Its builds were failing so its notifications were the ones getting through to my pull request. I fixed that problem by preventing that old Jenkins box from building my newest branches. Once the old Jenkins box stopped building, the notifications from the new Jenkins box made it through to Github.
Wrapping up
That's it! That's everything I intentionally configured. Please try out my configuration and see if it works for you. Let me know if I left anything out.
The hard part with configuring Jenkins with Github is that, although there are many guides, the suggestions often conflict with each other and very many are out of date (sometimes even official documentation is out of date).
Nonetheless, here are some Resources:
This is a good guide for Github Webhooks
Github's Whitepaper on CI with Jenkins (It doesn't explain much in detail but it gives a good overview)
Github pull request builder plugin
Semi-official SO post for showing build status on Github repo
GitHub has "add webhook" feature which is accessible in the repository settings --> Webhooks section. This has 4 inputs
1. Payload URl - Enter the Jenkins url
2. Content Type - application/json
3. Secret - this is optional if you want to configure secret
4. Which events would you like to trigger this webhook? - select the option "Let me select individual events"
Bunch of checkbox options are visible, check "Pull requests" option. This option will send a request to Jenkins when Pull request is opened
Next step is create a job in Jenkins which will listen to GitHub events and kick off the build
I want to trigger a Build in VSTS whenever a push is made to my repository in Github. I see that in settings in my repository in Github you can set up a webhook for VSTS.In fact I had this already working but changed the secret by accident and know I have no idea how to get the secret I have been trying to find it in vsts but not having any luck.
Please any help would be appreciated.
If you create a CI build definition in VSTS to build the github repo, VSTS will create a webhook for push event in the github repo (as the screen shot you showed).
And if you changed the secret incorrectly by accident, you can delete the webhook and restore it in VSTS web page. Detail steps as below:
First delete the webhook:
In github webhook -> Delete webhook -> Yes, delete webhook.
Then restore the webhook:
In VSTS web page -> edit the CI build definition -> Triggers Tab -> it will detect “The remote repository’s webhooks are missing or incorrect” -> Restore.
Now the webhook restored with the correct secret and it can send request successful when push event occur.
I've found many sites that describe how to trigger a build on a Jenkins machine whenever new code is pushed to a Github repository. One thing that keeps showing up repeatedly is to check the "Build when a change is pushed to GitHub" item under the Build Triggers section..
Unfortunately, no matter what I do I can't seem to get that item to show up as an option for me under Build Triggers.
I've even removed and re-installed Jenkins from scratch. When I install it, I just tell it to install all of the most common plugins. I've verified in the Jenkins configuration that the GitHub plugin is there.
What am I missing to trigger a build on a GitHub repo update?
According to https://wiki.jenkins-ci.org/display/JENKINS/GitHub+Plugin#GitHubPlugin-PluginInformation this was changed from
Build when a change is pushed to GitHub
to
GitHub hook trigger for GITScm polling
So it is sufficient to have GitHub Plugin installed.
How do you get VSTS to build when a PR is created in GitHub? I've tried several triggers in the VSTS build like refs/pull/*/merge and refs/pull/*/head. I have a build working when a commit is made to the master branch, but I can't get a build to trigger when a PR is created.
I get the following when a PR is created.
Also, the webhook history shows that a message was successfully posted to VSTS, but the build never starts.
The official Microsoft VSTS GitHub Integration extension now supports this directly.
I think it's the trigger. Try what's described in this blog post.
There is not an easy way to enable this today for PRs. It is on the VSTS feature backlog that we want to address soon.
The way to make it work today would be to do something like: add a webhook to call your own custom service endpoint. Within your service endpoint, you could then call into VSTS to queue a build, and the build would need a step to post success/fail back to GitHub.
In your custom service endpoint, you would need to make sure the user is authorized as a contributor on the GitHub repo.
On the new VSTS UI you can find it in Build Edit -> Triggers:
