Continuous integration creates a build loop

[Eldad Cohen]

Hi,

I am using Multibranch Job.

I have a Webhook for my repository in gilab which is triggered when there is a push to dev branch and then webhook starts the build in Jenkins

At the end of build process, I created and updated chaneglog file and push it to dev branch again which would trigger the webhook again and make a loop of builds in Jenkins.

Any suggestions ?

Thanks

I'm not sure what's available for Gitlab, but some other SCMs have a plugin that allows commits by certain authors be skipped/ignored.

https://github.com/jenkinsci/scm-trait-commit-skip-plugin for example.

If there is no such plugin for Gitlab, it might be easy enough to make one or contribute a gitlab implementation to an existing one.

Hi,

It's not the cleanest approach but we get around a similar issue by adding a specific string into the commit message( like "No Build")

then in the Jenkinsfile we look for that string and exit if we find it.

Thanks on the tip

Can you please elaborate how did you exit ?

Hi,

We use a when clause to run the stage or not based on finding

a specific string in the commit message

stage('Publish') {
    // if we dont find SKIP_PUBLISH in git log
    // then we proceed with push
    // note, we're checking the status of the grep command
    // not the output. grep status will be 0 if we find the
    // string and 1 if we dont find
    when {
        branch 'master'
        expression {
            grepStatus = sh(returnStatus: true,
                    script: 'git log -1 | grep  SKIP_PUBLISH')
            return 1 == grepStatus
        }

    }
