Jenkins Pipeline 並行執行多個任務

場景：前端業務使用了微服務架構，需要在一個主項目中編譯打包所有子項目。

1、創建一個流水線任務

2、填寫項目描述

3、編寫 pipeline 腳本

pipeline {

    agent any

    stages {
        stage("build console all") {
            steps {
                script {
                    def starting = 'prod-'
                    def ending = ""
                    def job_list = [
                        "woc-common",
                        "woc-ecs",
                        "woc-eip",
                        "woc-home",
                        "woc-person-center",
                        "woc-user-iam",
                        "woc-vpc",
                        "woc-console",
                        "woc-oss",
                        "woc-slb"
                    ]

                    def branches = [:]
                    MAX_CONCURRENT = 4

                    //創建fifo
                    latch = new java.util.concurrent.LinkedBlockingDeque(MAX_CONCURRENT)

                    //往fifo中，填入最大個數元素
                    for(int i=0; i<MAX_CONCURRENT; i++)
                        latch.offer("$i")

                    for(int i=0; i<job_list.size(); i++) {
                        def name = starting + job_list[i] + ending
                        branches[name] = {
                            def thing = null
                            waitUntil {
                                //獲取一個資源
                                thing = latch.pollFirst();
                                return thing != null;
                            }

                            try {
                                //執行job
                                build(job: name, propagate: false)
                            }

                            finally {
                                //釋放一個資源
                                latch.offer(thing)
                            }
                        }
                    }

                    timestamps {
                        parallel branches
                    }
                }
            }
        }
