Make jenkins auto build one a day but build only when there are source code changed

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.

Like this

SINCE=`curl http://192.168.0.1:8080/job/MyJava/lastStableBuild/buildTimestamp?format=dd-MMM-yyyy`

cd /opt/code/myjava/

git log --pretty="%h - %s" --author=gitster --since=$SINCE --before=$SINCE --no-merges -- t/

  • Post Build actions

    • Post build task
    • Log text: commit
    • Operation: AND
    • Script: Your script to build your Java

  • Jenkins text finder

    • Also search the console output
    • Regular expression: Could not match
    • Unstable if found
