Jenkins

Question

关于詹金斯版本。 2.164.2，copyArtifacts插件1.42，当运行声明性管道调用共享库脚本时，我得到了很好的旧 NotSerializableException WorkflowJob 错误，其中不可序列化（ Jenkins.instance.getItem(jobName) ）沿着 copyArtifacts 插件调用传递。

当我评论 copyArtifacts 部分或四个 def 行（def job 到 def requiredBuildNumber - 如果我替换 requiredBuildNumber.toString()带有数字，例如 selector: specific('256') .

我玩了几天，希望得到一些建议！

我的 Jenkins 文件：

pipeline {
agent { label 'windows' }

parameters {
    string(defaultValue: "JOB-NAME", description: '', name: 'getInfoFromJobName')
    string(defaultValue: "2", description: '', name: 'numberOfBuildsBack')
}

options {
    buildDiscarder(logRotator(numToKeepStr: '30'))
    disableConcurrentBuilds()
    timestamps()
    ansiColor('xterm')
}


stages {
    stage('Get artifacts') {
        steps {
            cleanWs()
            checkout scm

            getLabInfoFromPrevLab jobName: "${params.getInfoFromJobName}",
                    numberOfBuildsBack: "${params.numberOfBuildsBack}",
                    getSuccessfulBuild: false
        }
    }

共享库存放脚本的地方\vars\getLabInfoFromPrevLab。groovy:

def call(Map params = [:]) {

def jobName = params.jobName
def numberOfBuildsBack = params.get('numberOfBuildsBack', 0)
def getSuccessfulBuild = params.get('getSuccessfulBuild', true)


def job = Jenkins.instance.getItem(jobName)
def lastReferencedBuild = job.getLastBuild()
def lastReferencedBuildNumber = lastReferencedBuild?.number.toInteger()
def requiredBuildNumber = lastReferencedBuildNumber - numberOfBuildsBack.toInteger()

copyArtifacts(projectName: jobName,
        selector: specific(requiredBuildNumber.toString())
)

}

Answer 1

尝试在 copyArtifacts 之前丢弃所有使用 hudson 对象的变量：作业 = lastReferencedBuild = lastReferencedBuildNumber = null

Answer 2

针对您的问题：根据官方共享库 documentation、

Library classes cannot directly call steps

而根据pipeline steps reference，复制神器呢是一个步骤。

为了解决这个问题，文档为您提供了几个选项。我个人更喜欢在共享库中使用静态方法，因此可以将脚本传递到库并在那里调用步骤：

您的函数调用：

getLabInfoFromPrevLab
    script: this,
    jobName: "${params.getInfoFromJobName}",
    numberOfBuildsBack: "${params.numberOfBuildsBack}",
    getSuccessfulBuild: false

以及函数实现：

def call(Map params = [:]) {
    def jobName = params.jobName
    def numberOfBuildsBack = params.get('numberOfBuildsBack', 0)
    def getSuccessfulBuild = params.get('getSuccessfulBuild', true)

    params.script.copyArtifacts(projectName: jobName,
        selector: specific(requiredBuildNumber.toString())
)
