我有解决方案：
至少将Blue Ocean更新到版本1.22，才能正确查看管道。
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}BlueOcean管道示例1
