我有一个脚本，该脚本可以计算活动执行程序的数量。 该脚本在Jenkins控制台（https://url/jenkins/script）上运行良好，但是将其放置在管道中时会引发异常。我不知道要解决什么，因为所有println都显示正确的值。 

pipeline {
    agent any
    stages {
        stage('test') {
            steps {
                script {
                    runningBuilds = Jenkins.instance.getView('All').getBuilds().findAll() { it.getResult().equals(null) }
                    println("runung builds:"+runningBuilds)
                    a = runningBuilds.findIndexValues { name -> name =~ /(t)/ } 
                    println("just a= "+a)
                    size = a.size()
                    println ("size= "+size)
                    println ("end")
                }
            }
        }
    }
}

/ script网页的输出：

runung builds:[tst/cleanup_2 #2, tests/m-t1/isfile #9]
just a= [0, 1]
size= 2
end

控制台输出：

runung builds:[tests/t1 #113, tst/cleanup_2 #2, tests/m-t1/isfile #9]
[Pipeline] echo
just a= [0, 1, 2]
[Pipeline] echo
size= 3
[Pipeline] echo
end
[Pipeline] }
[Pipeline] // script
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline

Jenkins Pipeline使用Groovy CPS执行Groovy代码，与普通的Groovy语言相比，它具有一些局限性。像findAll()或findIndexValues()这样的操作不会序列化，因此必须以非CPS的方式执行才能生效。

  

为了提供耐久性，这意味着正在运行的Pipelines可以在Jenkins master重新启动后幸存，脚本化Pipeline必须将数据序列化回master。由于此设计要求，某些Groovy习惯用法（例如collection.each { item → /* perform operation */ }）未得到完全支持。有关更多信息，请参见JENKINS-27421和JENKINS-26481。

根据official Jenkins best practices guideline，您应该提取findAll()和findIndexValues()之类的操作，以分隔用@NonCPS注释的方法，以避免在非CPS方法中运行管道步骤。如果这样做，您将获得无法预测的结果。考虑以下示例：

pipeline {
    agent any
    stages {
        stage('test') {
            steps {
                script {
                    runningBuilds = findBuilds()
                    println("runung builds:"+runningBuilds)
                    a = findIndexValues(runningBuilds)
                    println("just a= "+a)
                    size = a.size()
                    println ("size= "+size)
                    println ("end")
                }
            }
        }
    }
}

@NonCPS
def findBuilds() {
    return Jenkins.instance.getView('All').getBuilds().findAll() { it.getResult().equals(null) }
}

@NonCPS
def findIndexValues(builds) {
    return builds.findIndexValues { name -> name =~ /(t)/ }
}

答案 1 :(得分：0)

您遇到不可序列化类型的问题（有关详细信息，请参见this）。

尝试在@NonCPS注释中使用以下语法：

@NonCPS
def print_details() {
    runningBuilds = Jenkins.instance.getView('All').getBuilds().findAll() { it.getResult().equals(null) }
    println("running builds:"+runningBuilds)
    a = runningBuilds.findIndexValues { name -> name =~ /(t)/ } 
    println("just a= "+a)
    size = a.size()
    println ("size= "+size)
    println ("end")
}

print_details()
