I have problem in configure jenkins to auto build and deploy java project. I want to build and deploy once a day. However this build only there are changes during the day. IF there is no changes, I don't want jenkins to auto build and deploy.
Note: that I used gitlab as source code management.
Can you help me with this configuration.?
Firstly, you should configure the Git SCM section at the top of the job config page to point to your GitLab repository.
Then you can use the built-in "Poll SCM" build trigger — this will periodically check whether your source code repository has changed — and if it has, a build of this job will be started.
If the repository has not changed since the last build, then no build will be started.
You can configure this trigger — whether using a cron-like syntax, or a shortcut like #daily or #midnight — so that Jenkins only checks the source repository once a day.
Additionally, you should make sure that the "ignore post-commit hooks" option is enabled. If you're using webhooks from your Git repository to start Jenkins jobs whenever a commit occurs, this option prevents your once-per-day job from being triggered for every Git commit.
Here's the detail document: "Jenkins CI integration"
http://doc.gitlab.com/ee/integration/jenkins.html
Update to match your comment.
You don't want to trigger the Jenkins build via webhook. It's ok.
You want to check the code change 1 time a day.
Example on Linux, build at 6:00 AM if there's any code change.

We uses notes (comments) from Gitlab to issue a couple of user-commands, for example retry a build that seems to have failed from a failed integration etc. We would now like to ask jenkins to stop a build. We have got the buildnumber from the comment (through a callback to to gitlab searching the comments) so we know what build to stop but now we stumbled on the problem. We don't seem to find an api-call to stop the build by buildnumber alone.
We could of course make a request to https://server/project/buildnumber/stop (same url as used by the ui) but then we have to enable the crumbIssuer and according to Ops open for a CSRF-attack.
Is there a way to do this operation from inside a pipeline?
Navigate to Manage Jenkins > Script Console.
Run the following script setting the job name and number of the hung build accordingly:
def build = Jenkins.instance.getItemByFullName("jobName").getBuildByNumber(jobNumber)
build.doStop()
build.doKill()
Otherwise you can create a separate pipeline job and configure the above script
Abort the job build from a cid node (if the previous option did not help):
Log in to any cid node.
Run:
cd /srv/volumes/jenkins/jobs/<job-name>/builds/
rm -rf <hung-build-number>
I'm beginning with Jenkins.
I want, that each time I do a git commit (or push?), that the jasmine test of my ionic project was executed and must work before the commit can be done.
In reality, it has 2 questions:
How execute jasmine test with Jenkins?
In this moment I execute the test with:
npm test
How can I do for executing this tests with a commit (or a push)?
Thanks
Best regards
You have two ways to achieve the task.
GIT Hook: From GIT after commit or push execute the Jasmine test
Jenkins Trigger with GIT Hook: From Jenkins check the repo and execute the Jasmine test
Hooks from GIT
Look for the hidden directory in your git repo, you'll find a directory called "hooks" and inside it many examples of hooks:
First list the content of your repo main directory:
ls -ltra
You should see something like:
m.ortiz.montealegre#CPX-XYR3G1DTHBU ~/-argentina/.git
$ vim hooks/
applypatch-msg.sample pre-applypatch.sample pre-push.sample update.sample
commit-msg.sample pre-commit.sample pre-rebase.sample
post-update.sample prepare-commit-msg.sample pre-receive.sample
You have a whole guide of how to setup hooks here.
In your case maybe update would do the thing:
update The update script is very similar to the pre-receive script,
except that it’s run once for each branch the pusher is trying to
update.
Triggers from Jenkins with GIT Hooks
In this one you'll setup your Jenkins project build trigger with "Poll SCM" but do not specify a schedule.
Then with a post-receive hook from GIT notify the Jenkins Job about the changes:
http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>?token=<get token from git to build remotely>
I found that example here.
Run the Jasmine tests
I don't know which O.S you're using but I hope it's a beautiful Linux box.
You can achieve pretty much the same with Jenkins. You need to consider the user (your user) and its permissions and check if the user which runs the Jenkins instance is allowed to execute the same.
Just create a new Jenkins Project and add a shell execution step with the test just like you said:
npm test
There are many questions regarding your particular environment, but I think that this will be a good guide for you.
There was a ticket about adding this functionality.
Finally the ticket was closed

At this point, I think it makes more sense to leave the code to do the watching of your specs and production code to one of the many external libraries that are built specifically for that.
The relate external library can be:
jasmine-node
nodemon
mochajs
gaze
Here is something I want to achieve:
I have a jenkins project which has 4 upstream projects. But I don't want to trigger this project when the upstream jobs are done building, but I want the trigger the project via remote API, which then waits on upstream projects until they are done building, if these projects are building.
Lets say all the 4 upstream projects can build the source code from any branch passed via API, but I want the downstream project to start only when a specific branch is passed to these upstream projects.
Scenario:
Lets say I have two clusters A and B, for the sake of this question, I want to deploy my code to cluster A, i.e front end and backend code. Now I have a project to build front end and 1 project to build backend (these two projects can build code for cluster A and B, based on the branch passed). Now, I have two deploy projects for cluster A which will deploy front end and backend. So, when I pass a branch to build code for cluster A, it will trigger the build projects. But now I only want these two deploy projects to start when this specific branch was passed.
If you want to control the builds remotely then use the Jerkins cli - I have found it very useful http://jenkinshost:8080/cli
You need to get the ssh key config right, add the public key of the user running the cli to the user you want to run the job in Jenkins using the Jenkins user configuration (not on the command line
Test key setup with
java -jar jenkins=cli.jar -s http://jenkinshost:8080 who-am-i
This should then report which user will be used to run the build in Jenkins
But I think you can use the Conditional Build Step plugin for your problem
https://wiki.jenkins-ci.org/display/JENKINS/Conditional+BuildStep+Plugin
This will allow you to put a conditional wrapper around a build step i.e.
if branch==branchA then
trigger step - deploy to clusterA
if branch==branchB then
trigger step - deploy to clusterB
Personally I find this plugin a bit clunky and it makes the job config page a little messy
Another solution I came up with was to always call the child job and then let it decide if it runs.
So I have a script step at the start of the child job to see if it should run
if [${branch}="Not the right branch name" ] ; then
echo "EXIT_GREEN"
exit 1
fi
You have now failed this job which would cause the parent job to go red but by using the Groovy Postbuild plugin https://wiki.jenkins-ci.org/display/JENKINS/Groovy+Postbuild+Plugin you can add a post build step like this
if (manager.logContains(".*EXIT_GREEN.*")) {
manager.addBadge("info.gif","This job had nothing to do")
manager.build.#result = hudson.model.Result.SUCCESS
}
Child job has run green (with an info icon against the build) but has actually not done anything. Obviously if the branch is one you want deploy then the first script step does not run the exit 1 and the job continues as normal
I've installed this p4 plugin in a Jenkins job. This scynces a workspace to the latest change and then builds. Now, under "Build Triggers", I've chosen "Build periodically" and set the job to run every 10 mins. Is there a way do trigger this Jenkins job when a new submit comes in to P4? Do I use the plugin or do I do something with "p4 trigger"? If so, how can I do this?
Thank you!
Under the same Build Triggers section, there is an option named Poll SCM. Enable that option. This option is present by default when you install Jenkins. It does exactly what you're looking for. It will trigger build as soon as it detects a new commit in P4. Although not necessary, it's good to enable Quiet period too. This option is under Advanced Project Options section (refer snapshot below). Also read Help (?) that's provided with every option to gain better understanding of what it does.
This is how to set up p4 url triggers.
Generate your API key, click your username in the top right > click configure > then generate a new API token!
In your build configuration check the "Trigger builds remotely (e.g., from scripts)", then write whatever you want as the authentication token I wrote "MadeUpToken"
The next step is to run this curl command:
curl -X POST -L --user your-jenkins-username:11170e251c58b2768d4d26bc1db3d6395f https://Your-Jenkins-URL.com/job/Local_UE4/build?token=MadeUpToken
I have a bash script that looks like this:
#!/bin/sh
previousRelease=`git describe --tags --match "release*" origin/release`
git diff --name-status $previousRelease..origin/release
Is there a way of having Jenkins execute it as part of a build process? The intention is to see a list of files that have changed since the last release, as a manual step to confirm that the release should go up. The user who has triggered the build needs to read the output and then confirm the release should go ahead.
Most things are possible to do in Jenkins but if it is the best way of doing it is another question.
To solve this I would use an approach with two jobs one for checking the diff (hock that one on to the git repository) The other job for doing the actual release.
The check diff job
1 Create a job of the type freestyle project with build type "execute shell" and run your script above. Add some prints at the end of the log to create a clickable link to manually start the release job with current git-id as argument.
Just printing an URL in console output will make it clickable so:
export GITID=`git log -n| grep and sed or awk something`
echo http://jenkins.example.com:8888/job/releaseme/buildWithParameters?label=$GITID¶meters=build
will create the accept changes user interface you requested.
The release job
2 Create another job(above I assumed you named it releaseme) let the job have one parameter as argument (tick "This build is parameterized") make let the argument be the git-id you would like to release. Create your release script in this job.
