脚本块中的NonSerializableException

Question

当我将test（）调用放入脚本中时，我得到了 NonSerializableException ，当我注释掉 A 行而未注释掉 B
行时，它工作得很好。

与test()在脚本内部和外部进行调用有什么区别？

我现在正在考虑的解决方法是使用when条件Jenkinsfile

更新 我怀疑该错误与需要“节点”块的命令有关

Jenkinsfile

#!/usr/bin/env groovy
import groovy.json.JsonSlurper

@NonCPS
def test() {
    sh "aws ecs update-service --cluster dev-cluster-name --service service-name --desired-count 0 --region us-west-2"
}

def deployDockerContainer() {
    script {
        def describeServices = sh(returnStdout: true, script: "aws ecs describe-services --region us-west-2 --cluster dev-cluster-name --services service-name").trim()
        def describeServicesJSON = new JsonSlurper().parseText(describeServices)

        if (describeServicesJSON.services.size() > 0 && describeServicesJSON.services[0].status.equals('ACTIVE')) {
            test() //A
        }
    }
    // test() //B
    sh "/usr/local/bin/ecs-cli ps --region us-west-2a --cluster dev-clustername"
}

pipeline {
    agent any

    environment {
        ENVIRONMENT = 'dev'
    }

    parameters {
        booleanParam(name: 'DEPLOY_TO_DEV', defaultValue: true, description: 'Deploy to Dev Environment?')
        booleanParam(name: 'DEPLOY_TO_TEST', defaultValue: false, description: 'Deploy to Test Environment?')
        booleanParam(name: 'DEPLOY_TO_PROD', defaultValue: false, description: 'Deploy to Production Environment?')
    }

    stages {
        stage('DEV:Deploy') {
            when {
                expression {
                    return params.DEPLOY_TO_DEV
                }
            }
            environment {
                ENVIRONMENT = 'dev'
            }
            steps {
                deployDockerContainer()
            }
        }
    }
}

Answer 1

首先JsonSlurper是不可序列化的。如果要使用它，则必须将其封装到@NonCPS方法中。

其次，您不能在@NonCPS方法中使用任何cps方法，例如sh。

第三，如果您不遵循这些规则，有时管道（cps代码）运行程序不会立即引发错误。有时，对脚本本身进行一些更改后会引发错误。
