Jenkins Pipeline sleep(10) 阻止功能完成

Question

我在 Jenkinsfile 中发现了一个奇怪的 Groovy 代码问题:

@NonCPS
def test() {
  println "Start"
  sleep(10)
  println "Stop"
}

问题是，在休眠 10 秒后，代码永远不会到达 println "Stop" .
看起来， sleep 在 10 秒后返回并运行下一个管道步骤。

输出只是:

[Pipieline] echo
Start
[Pipeline] sleep
Sleeping for 10 sec
[Pipeline] }
 ... next pipeline steps

有没有人有同样的问题？

当您调用 sleep(10)在您的 Groovy 脚本中，Workflow CPS 插件执行 SleepStep 而不是 DefaultGroovyStaticMethods.sleep(Object self, long time) .您的问题是由 @NonCPS 引起的功能(感谢 mkobit 的建议!)。考虑以下示例:

node {
    stage("Test") {
        test()
    }
}

@NonCPS
def test() {
    echo "Start"
    sleep(5)
    echo "Stop"
}

输出:

[Pipeline] node
Running on Jenkins in /var/jenkins_home/workspace/test-pipeline
[Pipeline] {
[Pipeline] stage
[Pipeline] { (Test)
[Pipeline] echo
Start
[Pipeline] sleep
Sleeping for 5 sec
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS

没有 Stop从管道运行中回显。现在，如果我们只删除 @NonCPS我们在管道中调用的函数的注释:

node {
    stage("Test") {
        test()
    }
}

def test() {
    echo "Start"
    sleep(5)
    echo "Stop"
}

事情发生了变化， Stop按预期得到回显:

Started by user admin
[Pipeline] node
Running on Jenkins in /var/jenkins_home/workspace/test-pipeline
[Pipeline] {
[Pipeline] stage
[Pipeline] { (Test)
[Pipeline] echo
Start
[Pipeline] sleep
Sleeping for 5 sec
[Pipeline] echo
Stop
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS
