Jenkins 2.161

我有一个脚本，它计算活跃的执行者的数量。这个脚本在Jenkins控制台(https://url/jenkins/script)上工作得很好，但是当它放在管道中时会抛出异常。我不知道该怎么解决，因为所有println都显示正确的值。

代码语言：javascript
复制
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")
                }
            }
        }
    }
}

来自/script网页的输出：

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

控制台输出：

代码语言：javascript
复制
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，它有一些限制。像findAll()或findIndexValues()这样的操作不是序列化的，因此它们必须以非CPS方式执行才能生效。

为了提供持久性，这意味着正在运行的管道可以在重新启动Jenkins主服务器后幸存下来，脚本管道必须将数据序列化回主服务器。由于这种设计要求，一些Groovy语言，如collection.each { item → /* perform operation */ }，并不完全支持。有关详细信息，请参阅JENKINS-27421和JENKINS-26481。

来源：

根据official Jenkins best practices guideline，您应该提取像findAll()和findIndexValues()这样的操作来分离使用@NonCPS注释的方法，以避免在非CPS方法中运行流水线步骤。如果你这样做，你将得到不可预知的结果。考虑以下示例：

代码语言：javascript
复制
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)/ }
}

不可序列化类型有问题(有关详细信息，请参阅this )。

尝试将此语法用于@NonCPS注释：

代码语言：javascript
复制
@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()
