为Groovy提供列表以循环运行任务多次

Question

我有在Groovy中定义的列表，如：

all_services:[processor-create, processor-update, read-service]

我怎样才能将这个列表提供给for循环播放变量$ {service}

script {

    sh("""

    ansible-playbook -i localhost, cleanup.yml --extra-vars=@${service}.yml
    """)
    ...

因此，如果列表有2个项目，则应该运行该剧本，然后每个项目必须运行2次。

让我说清楚。

我有groovy脚本它有多个阶段：

stages {
    stage('Prepare') {
        agent any
        steps {
            script {
                if (params.DEPLOY_ALL_SERVICES == true){
                   all_services = new ArrayList(Arrays.asList("${params.ALL_SERVICES}".split("\\+")))
                   println "all_services:" + all_services
                } else{
                   if (params.DEPLOY_ALL_EX_SERVICES == true){
                       all_ex_services = new ArrayList(Arrays.asList("${params.ALL_EX_SERVICES}".split("\\+")))
                       println "deploy all ex services:" + all_account_services
                       all_services += all_ex_services
                   }
                   println "All Services:" + all_services
                }
            }
        }
    }
    stage('Create conf'){
        agent any
        steps {
            script {
                def services = "$all_services"
                println services    // it works till here, it's printing the list, if add single quotes to list then hopefully it should loop through it
                services.each {service ->
                    sh("""
                      ansible-playbook -i localhost, cleanup.yml --extra-vars=@${service}.yml
                     """)
                 }
            }
        }
    }
}

当我执行管道时，它能够在控制台上打印列表，但是无法将该列表提供给def services =“$ all_services”，它没有得到所有列表来执行循环。

控制台输出println服务：

       [processor-create, processor-update, ex-service]

你的问题确实不够明确，无法确切知道你在寻找什么，但是下面的groovy代码：

def services = ['processor-create', 'processor-update', 'read-service']

services.each { service -> 
  sh("ansible-playbook -i localhost, cleanup.yml --extra-vars=@${service}.yml")
}

def sh(str) {
  println "fake execution>> \n${str}\n"
}

演示iteration of a collection和string interpolation。将上述内容保存在solution.groovy中并执行它会产生：

~> groovy solution.groovy
fake execution>>
ansible-playbook -i localhost, cleanup.yml [email protected]

fake execution>>
ansible-playbook -i localhost, cleanup.yml [email protected]

fake execution>>
ansible-playbook -i localhost, cleanup.yml [email protected]

应该注意的是，由于上面的代码使用的是纯粹的groovy并且在groovy中没有开箱即用的script或sh，我嘲笑了sh方法只是在stdout上打印结果。
