如何在Jenkins声明式管道中循环参数化并行阶段？（或者脚本化的管道，如果声明式不能）

这是我简单的伪示例。如何循环（“部署serverN”）阶段？

数组可能具有1..n变量。

我不想重复代码。詹金斯管道中一定有办法吗？还是我应该使用矩阵。我已经尝试了一些，但是没有成功。

@Library('adm-jenkins-lib@trunk')

def SERVERS = ['server1.com','server2.com',...]

deployPipeline([servers: SERVERS, manage_tasks: TASKS])

...
def call(Map params) {  
    pipeline {
        agent any
        environment {
        }
        stages {
            stage ('common task') {
            }       
            stage ('Deploying..') { 
                parallel {
                    stage ('deploy server1') {
                        stages {
                            stage ('deploy tasks #1') {
                                steps { ... }
                            }
                            stage ('deploy tasks #2') {
                                steps { ... }
                            }
                        }
                    stage ('deploy server2') {
                        stages {
                            stage ('deploy tasks #1') {
                                steps { ... }
                            }
                            stage ('deploy tasks #2') {
                                steps { ... }
                            }
                        }
                    }
                }
            }
        }
    }
}

我也尝试过这种方法，但是由于前一阶段不依赖于下一阶段，所以它并不是完美的。

            stage ('deploy serverX') {
                when { expression { params.manage_tasks =~ /task01/ } }
                steps {
                    script {
                        servers = params.servers
                        servers.each { server ->
                            deploys[server] = {
                                sh "run task#1 stuff.."
                            }
                        }
                        parallel deploys
                    }
                }
            }

它在Blue Ocean中应该看起来像这样（但是动态创建的）： It should look like this in Blue Ocean

我有解决方法：

至少将Blue Ocean更新到版本1.22，以正确查看管道。

按照@ zett42的建议安装库https://github.com/comquent/imperative-when。

此示例是脚本管道。（我没有找到声明性管道的解决方案）

@Library('adm-jenkins-lib@trunk') _

properties([
    parameters([
        string(name: 'countTotal', defaultValue: '4'),
        choice(name: 'servers', choices: ['all', '1', '2','3','4'], description: 'Run on specific platform'),
        choice(name: 'manage_steps', choices: ['all_tasks','common_task','deploy_task','test_task'], description: 'Choose task')
    ])
])

node{
    stage('common task'){
        when(params.manage_steps ==~ /common_task|all_tasks/) {
            sh "echo common task"   
        }
    }
    def stages = [failFast: true]
    for (int i = 1; i < params.countTotal.toInteger()+1; i++) {
        if (params.servers == 'all' || params.servers == i.toString() )
        {
            def vmNumber = i //alias the loop variable to refer it in the closure
            stages["server${vmNumber}"] = {
                stage("deploy ${vmNumber}") {
                        when(params.manage_steps ==~ /deploy_task|all_tasks/) {
                        sh "echo deploy; sleep 5"
                  }
                }
                stage("test ${vmNumber}") {
                        when(params.manage_steps ==~ /test_task|all_tasks/) {
                        sh "echo testing; sleep 5"
                        }
                }
            }
        }
    }
    parallel stages
}
