How to trigger only when there is a specific word in the PR title?

[soondl]

I want to trigger build only when there is a string "[iOS]" in PR title. For example, [iOS] Fix view logic

I found the parameter "skip build phrase" and I wrote it as follows to match the phrase that does not contain "iOS", but it didn't work.

Is there any other way? Thank you.

I don't think REGEX works here. I also want to know how to make this work

I also had the same problem as you. I could not find the right answer, but my solution was the following:

Let all PR trigger a build.

Then, on the pipeline, you simply do the following:

environment {
    PULL_TITLE = "${ghprbPullTitle}"
}
stage('Skip Build') {
    when {
        expression {
            return !(env.PULL_TITLE =~ /\b(DEV|QA|STG|PRD|DEVOPS)\b/)
        }
    }
    steps {
        script {
            echo "PR title does not contain any of the specified words. Skipping the build."
            currentBuild.result = 'ABORTED'
            error("Aborting the build.")
        }
    }
}

If the PR title doesn't have the words I want, then skip the build.

It will show up like this:
