Jenkins-与copyArtifacts，NotSerializableException WorkflowJob共享的库

时间：2019-05-13 10:20:48

标签： jenkins groovy jenkins-pipeline jenkins-plugins jenkins-groovy

在詹金斯版本上。 2.164.2，copyArtifacts插件1.42， 当运行声明式管道调用共享的lib脚本时，出现老的NotSerializableException WorkflowJob错误，在该管道中通过copyArtifacts插件调用传递了不可序列化的（Jenkins.instance.getItem（jobName））。

当我注释copyArtifacts部分或四行def行（从def job到def requiredBuildNumber时，错误消失了-如果我用数字替换requiredBuildNumber.toString（），则会成功复制工件，例如selector: specific('256')。

我玩了几天，请给我一些建议！

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
        }
    }

共享库中包含脚本\ vars \ getLabInfoFromPrevLab.groovy的位置：

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())
)

}

尝试在copyArtifacts之前丢弃所有使用var的hudson对象： job = lastReferencedBuild = lastReferencedBuildNumber = null

具体针对您的问题：根据官方共享库documentation，

  

图书馆类不能直接调用步骤

根据pipeline steps reference，复制工件是一个步骤。

要解决此问题，文档提供了几个选项。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中，然后调用以下步骤：

您的函数调用：

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

函数实现：

def call(Map parms = [:]) {
    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())
)
