Jenkins Pipeline sleep（10）阻止功能完成

Question

我在Jenkinsfile中发现了Groovy代码的奇怪问题：

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

事实是，睡眠10秒钟之后，代码就再也无法进入了println "Stop"。
看来，睡眠会在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

有人遇到过同样的问题吗？

当您sleep(10)在 Groovy 脚本内部调用时，工作流 CPS 插件将执行SleepStep而不是DefaultGroovyStaticMethods.sleep(Object self, long time). 你的问题是由@NonCPS函数引起的（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

Stop管道运行没有回显。现在，如果我们只@NonCPS从管道中调用的函数中删除注释：

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

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

事情发生变化并按Stop预期得到回应：

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
