Jenkins trigger build every 8 commits only - How to do this?

Question

I have a declarative pipeline I made. I'm trying to make Jenkins trigger build after every 8 commits only. I'm new to Jenkins, how do I trigger a build based on commit number?

Answer 1

Provided each commit triggers a build:

pipeline
    agent any
    stages {
        stage('Check 8 commits') {
            steps {
                def build_num = env.BUILD_NUMBER as int
                if (build_num % 8 != 0) {
                    error "This is not 8th commit"
                }
            }
        }
    }
}
