Jenkinsfile takeWhile 在 Jenkins 上返回 Boolean，但在实际的 groovy 中返回 ArrayList。为什么？

Question

所以，我在 Jenkinsfile 中有一些代码，takeWhile 函数在 jenkins 中运行时返回一个 bool 值，但在实际的 groovy 中返回一个列表(正如预期的那样!)执行。整个脚本在本地运行结束，但在 jenkins 中失败，因为我将 takeWhile 的结果用作 List，即使 jenkins 版本是 Boolean

我的同事推测插件安全管理器正在干扰。这是我唯一能想到的。

本地 groovy 版本:

$ groovy -version
Groovy Version: 2.4.14 JVM: 1.8.0_131 Vendor: Oracle Corporation OS: Mac OS X

Jenkins 版本:

Jenkins ver. 2.107.3

代码:

#!/usr/bin/env groovy

try {
    def deployTo = [
            'pre' : ['us-east-1'],
            'int' : ['us-east-1'],
            's1'  : ['ca-central-1', 'us-east-1'],
            'demo': ['us-east-1'],
    ].collectMany { k, v -> v.collect { r -> [k, r] } }

    def failure = deployTo.findResult { entry ->
        def result = 0
        stage("Deploying to:\n${entry[0]}\n(${entry[1]})") {
            println("stage deploy")

        }
        return new Random().nextBoolean() ? entry : null
    }
    println("deployto is a : ${deployTo.class}")
    println("deploy to: ${deployTo}")
    def takeWhile = deployTo.takeWhile { it != failure }
    println("takeWhile is a : ${takeWhile.class}")
    println("takeWhile to: ${takeWhile}")
    takeWhile.each { toRollback ->
        println("torollback is a ${toRollback.class}")
        stage("Rolling back to:\n${toRollback[0]}\n(${toRollback[1]})") {
            println("stage rollback")
        }
    }
} catch (e) {
    println(e.getStackTrace().join('\n'))
    println(e.class)
    println(e.message)
    throw e
}

本地常规输出:

Deploying to:
pre
(us-east-1)
stage deploy
Deploying to:
int
(us-east-1)
stage deploy
deployto is a : class java.util.ArrayList

这类似于我提交的问题 (JENKINS-49826)。这是 Jenkins Pipeline 中的 CPS 编译问题。我会针对 workflow-cps-plugin 提交错误因为这绝对不是预期的行为。

与此同时，我会将您的takeWhile 调用移动到一个@NonCPS 注释方法并将所有内容作为参数传递。参见 this question and answer for some information on @NonCPS .

这是您的示例，简化为一个小型复制器，以及您可以将逻辑移动到 @NonCPS 的方法:

final deployTo = [
  'pre' : ['us-east-1'],
  'int' : ['us-east-1'],
  's1'  : ['ca-central-1', 'us-east-1'],
  'demo': ['us-east-1'],
].collectMany { k, v -> v.collect { r -> [k, r] } }
final failure = [pre: 'us-east-1']

echo "${deployTo}"
echo "${deployTo.getClass()}"

def takeWhile = deployTo.takeWhile { it != failure }
println("takeWhile is a : ${takeWhile.class}")
println("takeWhile to: ${takeWhile}")

def nonCpsUsage = nonCpsTakeWhile(deployTo, failure)
println("nonCpsTakeWhile is a : ${nonCpsUsage.class}")
println("nonCpsTakeWhile to: ${nonCpsUsage}")

@NonCPS
def nonCpsTakeWhile(final d, final f) {
  return d.takeWhile { it != f }
}

输出:

请注意 @NonCPS 的返回类型是 java.util.ArrayList 与 java.lang.Boolean 的不同类型。
