jenkins - 如何将 jenkins 脚本化管道转换为声明性管道

Question

有人可以帮我将下面的 Jenkins 脚本管道转换为声明性管道吗

node('agent') {

if ( ! "${GIT_BRANCH}".isEmpty()) {
    branch="${GIT_BRANCH}"
} else {
    echo 'The git branch is not provided, exiting..'
    sh 'exit 1'
}

version = extract_version("${GIT_BRANCH}")

if ( "${GIT_BRANCH}".contains("feature")) {
    currentBuild.displayName = "${version}-SNAPSHOT-${env.BUILD_ID}"
}
else {
    currentBuild.displayName = "${version}-${env.BUILD_ID}"
 }
}

我正在尝试检查是否提供了 git branch 并根据 git branch 动态设置 jenkins build id

pipeline {
agent {
        label 'agent'
    }
    stages{
        stage('stag1'){
            steps {
                script {
                    if ( ! "${GIT_BRANCH}".isEmpty()) {
                        branch="${GIT_BRANCH}"
                    } else {
                        echo 'The git branch is not provided, exiting..'
                        sh 'exit 1'
                    }

                    version = extract_version("${GIT_BRANCH}")

                    if ( "${GIT_BRANCH}".contains("feature")) {
                        currentBuild.displayName = "${version}-SNAPSHOT-${env.BUILD_ID}"
                    }
                    else {
                        currentBuild.displayName = "${version}-${env.BUILD_ID}"
                    }
                }
            }           
        }
    }
}
