这个共享库中的"不可序列化"是什么,我该如何解决？

Question

使用Jenkins管道插件时,构建失败并出现java.io.NotSerializableException错误,如下所示:

java.io.NotSerializableException: org.codehaus.groovy.control.ErrorCollector

Finished: FAILURE

当我使用带有一些import语句的自定义库时会发生这种情况.我已经尝试了几件事,比如用@NonCPS封装调用方法,但错误仍然存​​在.

管道脚本

#!groovy
@Library('utils')

pipeline {
    agent any
    stages {
        stage('Run Script') {
            script {
                myScript param1
            }
        }
    }
}

瓦尔/ myScript.groovy

import com.company.jenkins.utils

def call(String param = "test") {
    def libScript = LibScript(this)
    libScript.printMessage("Hello World")
}

SRC/COM /公司/詹金斯/ utils的/ LibScript

package com.company.jenkins.utils;

// This import works fine
import groovy.json.*

// This one fails
import groovyx.net.http.RESTClient

class LibScript implements Serializable {
    def steps
    def client

    LibScript(steps) { this.steps = steps }

    def printMessage(String message) { steps.echo "Saying: " message }

    // This also fails
    @NonCPS
    def doSomething() { client = new groovyx.net.http.RESTClient( 'https://somehost/' ) }
}

使用的版本:

• 詹金斯:2.19.3
• 管道插件:2.5
• Pipeline Shared Groovy Libraries插件:2.7

会出现此错误是因为compilation error. 这不是一个很好的堆栈跟踪。但是您将 anon serializable object作为变量之一或在字符串中间（可以将变量值设置为 '.."$var"..' ）。为此，我附上两个链接。请仔细阅读它们，您就会明白出了什么问题。请一步步运行，了解哪里出了问题。
