脚本块中的NonSerializableException [英] NonSerializableException inside script block

查看：180
本文介绍了脚本块中的NonSerializableException的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

当我将test()调用放入脚本中时，当我注释掉 A 行而未注释掉 B 行时，我得到了 NonSerializableException >，就可以了.

I get a NonSerializableException when i put my test() call inside a script, when I commented out line A and uncommented out line B, it works just fine.

与在脚本内部和外部调用test()有什么区别?

What's the difference from calling test() inside a script and outside of it?

我现在正在考虑的解决方法是将when条件用于Jenkinsfile

The workaround I'm considering for now is to use the when conditions for Jenkinsfile

更新 我怀疑该错误与

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

推荐答案

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

First of all JsonSlurperis not serializable. If you want to use it you have to encapsulate it into a @NonCPS method.

第二，您不能在@NonCPS方法中使用任何cps方法，例如sh.

Second you cannot use any cps methods from within a @NonCPS method, like 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.

Third, sometimes the pipeline (cps code) runner does not immediately throw an error if you do not follow those rules. Sometimes the error is thrown after doing some changes to the script which itself are correct.
