I'm trying to connect Gitlab CE 8.16 with Jenkins 2.46.1 using the GitLab hook plugin 1.4 to trigger builds when push or merge.
So I checked "Build when a change is pushed to GitLab", copied the GitLab CI Service URL: http://server:port/project/my-project and the security token, to gitlab webhook, disabled ssl verification and when I clicked on Test, I got this error :
Hook execution failed: execution expired
What am I doing wrong, please? How can I make it work?
There are a few things that are needed to make it work, there is documentation here:
https://github.com/jenkinsci/gitlab-plugin#global-plugin-configuration
So:
Make sure the jenkins user that you use on the GitLab side has the proper permissions - it needs project access and the APITOKEN needs to be there
Create the webhook on the project in GitLab that corresponds to the project in Jenkins (the Jenkins project that uses the git repo you are working with)
In GitLab, when you create webhooks to trigger Jenkins jobs, use this format for the URL and do not enter anything for 'Secret Token': https://USERID:APITOKEN#JENKINS_URL/project/YOUR_JOB
You can use a non-https link too and skip SSL verification if the certificate is not valid. Either way, the gitlab server has to be able to connect to the name and port you are using there.
Hit test and it should work, if not, you might not be able to connect to the server. Make sure your Jenkins server is listening on the URL and port that you are using, the error seems to be related to that not being right.
It's possible that GitLab server is not allowed to connect to the internet, or to the network you have the Jenkins server on, or there might be a firewall blocking the port you try to connect to (80/443) on the local Jenkins machine.
Try to do for example a curl to the Jenkins server and see what comes back:
curl http://you.jenkins.fqdn/
If you don't get something like:
<html><head><meta http-equiv='refresh' content='1;url=/loginEntry?from=%2F'/><script>window.location.replace('/loginEntry?from=%2F');</script></head><body style='background-color:white; color:white;'>
Authentication required
<!--
You are authenticated as: anonymous
Groups that you are in:
Permission you need to have (but didn't): hudson.model.Hudson.Read
... which is implied by: hudson.security.Permission.GenericRead
... which is implied by: hudson.model.Hudson.Administer
-->
</body></html>
then you cannot connect.
If it's not the Jenkins server where the issue is, you need to ask the network people that manage the server about it.
Hope that helps, good luck!
Make sure to use the latest 1.4 GitLab hook plugin (1.4.3, March 2016)
Look into your GitLab production.log, as in this issue, and see if this is a proxy configuration problem.
You should at least the context of that error message.
Here is what worked for me:
Ensure there is a merge request, even if you don't intend to actually merge any branches.
Go to branches -> select 'merge request' for a branch to merge -> create the request
Now try to test the integration.

I want Jenkins to trigger build automatically when GitHub PR created, but it seems GitHub unable to communicate with Jenkins, getting an error in GitHub webhook as "We couldn’t deliver this payload: Service Timeout" which is automatically created after below configurations.
my Jenkins server is behind a firewall and I have installed & configured "Github pull request builder".
I have created a job with GitHub project and with below configurations. and
Jenkins proxy test
Any other configuration needed or am I doing something wrong ???
Is your jenkins server accessible from the internet? if not, you will need to open your firewall to allow access from github IPs specifically.
You can find githubs IP addresses on the meta endpoint for the api subdomain:
https://api.github.com/meta
In "Advanced" tab of GHPR select the below option:
Build every pull request automatically without asking (Dangerous!).
Put the name of the branch in Whitelist Target Branches.
I deploy Jenkins and GitLab using Docker (locally), both are connected with each other.
One of the problems (not very important) is with SSH. I create ssh key inside Jenkins container and set it to GitLab, but when Jenkins try to checkout the repository throws "Permission Denied". So, executing Jenkins bash, try to run git command and what's happen? GitLab container needs a password for access. Searching, and trying to do as a virtualized server, no works. Whatever, I solved using user and password (I don't like, but works).
The important problem. I don't have any problem creatin, and running, a job (using pipelines). The job download the world from GitLab and send the result to GitLab. The problem, after add a webhook with Jenkins URL to GitLab, push something but nothing happens in Jenkins, not trigger the job.
Anyone can help me?
Thanks!!
Is your webhook working correctly ?? are you able to send/receive request and response, if not refer to
Github webhook URL config issue? How to fix it?
When you push does it trigger a request ? can you try hitting it with postman if you do have a request. If you can provide more information, then it will be helpful :)
I'd like to configure bitbutcket to trigger a jenkins build.
I've spent some time researching this and all the answers are from a few years ago, and have not found any guides because things seem to have changed since.
What I'm trying to do:
A bitbucket push to a particular branch triggers a build.
What I've got:
Bitbucket web hooks which fires HTTP request to Jenkins on a push to any branch. I've also installed the Bitbucket plugin on Jenkins which adds a check box in the job config Build when a change is pushed to BitBucket. This checkbox doesnt seem to work (maybe I set it up wrong? minimal docs for this), despite me pushing to the configured branch in the SCM section.
Problem 1: Bitbucket does not fire a GET, but another request which causes a 403. I tested with postman, and it works with a GET, but not a POST.
Problem 2: This HTTP build request is fired on pushes to any branch. While the build is still restricted to a particular branch, it seems unnecessary to be rebuilding all the time.
How do i address these issues? Bitbucket does not seem to be very flexible in customizing this. The Jenkins plugin for bitbucket has a lot of 'bad' reviews. How are developers currently doing this?
SPECIFIC solution for Jenkins CI server--Webhook to Jenkins for Bitbucket plugin has been commercialized in latest version of Bit-Bucket and the current price is around $4800 which was earlier a free offering, because of this, guys who want to save their bucks, can go to the alternative solution by using webhooks feature of bit-bucket:-
Steps to create a webhook:-
BitBucket Side
1) Go to your bitbucket repo, click on Repository Setting, under WORKFLOW got for WEBHOOKS option and create a webhook.
a) creation of webhook:- URL https://JenkinsserverURL/git/notifyCommit?url=https://bitbucket.repository-link/repository.git
b) In the name tab, give any name of your choice
c) click on TEST CONNECTION before saving it. Make sure you get http status 200
d) View details your logs, check your request and response is correct.
Things to take care of from
Jenkins Side:-
1) Make sure repository mentioned in bitbucket webhook is used in Jenkins job.
2) In SCM option, activate/select Poll SCM option, don't mention anything in the schedule, leave it blank.
3) configure rest job,
Whenever your git repo observes any change an automatic build will get triggered in Jenkins. By default push trigger is activated and if you want to activate other action, please select those events while creating webhook.
***to specify the branch in repository webhook:-
http://yourserver/git/notifyCommit?url=<URL of the Git repository>[&branches=branch1[,branch2]*][&sha1=<commit ID>]
Cheers,
Is your Jenkins URL accessible from your bitbucket server? If yes that it should be fairly simple to do it. You add the webhook in your repository as http://<url-of-jenkins>/git/notifyCommit?url=<url-of-repository>. When jenkins receives this POST, it automatically triggers builds on those jobs that use this git repo with that URL you give in webhook.
But you also need to make sure your Build Schedule is set to empty for those jobs. otherwise it wont get triggered. You can specify a branch in webhook URL too
See the Push Notification from repository here
https://wiki.jenkins.io/display/JENKINS/Git+Plugin
For anyone here after July 2022, here are the simple steps I followed to make it work.
Create a live Jenkins URL
First, create a tunnel from a live URL to your local Jenkins URL using ngrok because using locahost:8080 directly as your webhook URL on bitbucket will simply not work as bitbucket does not recognize your local computer.
ps: ngrok claims to be the fastest way to put anything on the internet and I agree,
you can use it beyond Jenkins once you know the trick,
such as quickly handling out your localhost react app for testing by your friends
out of your local network
To do this is simple. For Linux:
Install ngrok snap install ngrok
Add authtoken ngrok config add-authtoken <token>
Don't have an auth token, sign up
Start a tunnel on your Jenkins port eg ngrok http 8080
To know more and for other OS, check ngrok download page
You will then get a response like
ngrok (Ctrl+C to quit)
Hello World! https://ngrok.com/next-generation
Session Status online
Account <your email>#<domain>.com (Plan: <plan type>)
Version 3.0.6
Region Europe (eu)
Latency 162ms
Web Interface <web interface url>
Forwarding https://<your-assigned-host>.ngrok.io -> http://localhost:8080
Basically, the web interface URL on click gives you a web interface to inspect all the requests being tunnelled from your ngrok live URL to your local host.
Forwarding URL is basically a proxy to your localhost, so when you want to configure webhook, instead of using locahost:8080, you replace it with ngrok URL eg https://syue-162-34-12-01.eu.ngrok.io and all requests get tunnelled to localhost:8080
Hook up the URL on bitbucket cloud
Secondly, configure your Bitbucket repository with a Webhook, using URL JENKINS_URL/bitbucket-hook/ (no need for credentials but do remember the trailing slash) eg https://syue-162-34-12-01.eu.ngrok.io/bitbucket-hook/
If you are using bitbucket server and not cloud or you want to know more, the bitbucket plugin documentation for Jenkins is pretty straightforward and easily understandable, see bitbucket plugin
then you can inspect all your webhook requests on the web interface URL or via your terminal as well as check your build logs on Jenkins via your localhost port or ngrok live url.
Disclaimer: I have not figured out how to enable build only when a specific branch change but you can configure jenkins to only build a specific branch or any branch created as your need may demand, check Source Code Management and Build Triggers
There are lots of question on here about Permission denied (publickey) errors when using the Jenkins git plugin.
Can someone explain the authentication flow this plugin uses to check out a repository? I can't find a good description on the plugin page.
I want to just SSH into the build slave, checkout the repository there, then run my job, but clearly that is not how it works.
I guess I could add my credentials to the jenkins master, but I dont want any code there. I want it on my build slave.
Issue has nothing to do with git really. As their documentation states, it relies on git runtime which in its turn relies on system environment when it comes to secure connections. Ssh requires client to have valid key to connect and fails to that message if client does not provide one. Without any additional actions, key is not injected into environment, so client could not provide any valid key.
What you actually can use is ssh agent plugin. That allows to add key to ssh-agent on slave that will be catched up by git.
I have a Jenkins server that is behind a firewall (Boss's Orders), can't be accessed outside of the office unless on the vpn. I'm trying to set up continous integration for our rails team. I have the job to run our tests going whenever there is a commit/merge in the publicly hosted repo on github.com. My question is, how do I go about setting up my server to be able to push the status of the related tests to the pull request located on github to ensure it is unable to be merged unless all the tests passed.
Unless your firewall prevents outgoing connections, your Jenkins instance should be able to update the status on github without problems.
I found that there was a post status to Github in my post build options.
That successfully gave me the results I wanted.
