【问题描述】：

在运行我的 Java Groovy 脚本并更新到最新的 Groovy 管道时。感谢您的帮助。

我收到此错误，发生异常：在对象 org.jenkinsci.plugins.workflow.cps.CpsThreadGroup@3123aac2 对象中的字段线程中的字段程序中的字段 e 中的字段调用者的字段本地人中导致：java.io.NotSerializableException： hudson.model.Run$Artifact 我认为有问题的代码是

stage('Retrieve Code') {
        FileCacheCountCheck();
        def job = jenkins.model.Jenkins.instance.getItem("pipeline.preview.build")
        def build = job.getBuildByNumber(buildNumber)
        def art = build.artifacts[0]
        def file = art.file
        def targetPath = pwd()
        "rm -rf ${targetPath}/output".execute().text 
        "rm -rf ${targetPath}/script".execute().text 
        touch file: "${targetPath}/output/package.tmp"
        "cp ${file} ${targetPath}/output/package.zip".execute().text
        "cp -R ${targetPath}@script/ ${targetPath}/script/".execute().text 
                    }
stage('Stash Package') {

def targetPath = pwd() stash 包括：'output/**'，名称：'package'

根据这篇文章，https://github.com/jenkinsci/pipeline-plugin/blob/master/TUTORIAL.md#serializing-local-variables我尝试使用

@NonCPS
stage('Retrieve Code') {
    FileCacheCountCheck();
    @NonCPS
    def job = jenkins.model.Jenkins.instance.getItem("pipeline.preview.build")
    @NonCPS
    def build = job.getBuildByNumber(buildNumber)
    @NonCPS
    def art = build.artifacts[0]
    @NonCPS 
    def file = art.file
    @NonCPS
    def targetPath = pwd()
    "rm -rf ${targetPath}/output".execute().text 
    "rm -rf ${targetPath}/script".execute().text 
    touch file: "${targetPath}/output/package.tmp"
    "cp ${file} ${targetPath}/output/package.zip".execute().text
    "cp -R ${targetPath}@script/ ${targetPath}/script/".execute().text 
                }
stage('Stash Package') {
    @NonCPS
    def targetPath = pwd()
    stash includes: 'output/**', name: 'package' 
                        }

标签： jenkins groovy jenkins-pipeline

【解决方案1】：

根据article ：最安全的方法是在标有注释@NonCPS 的方法中隔离使用不可序列化状态

只需声明一个函数并将不可序列化的调用/步骤放入其中

@NonCPS  --- Once I removed this it worked. Also had to pass buildnumber as a parameter
def getArtifactPath(){
    def job = jenkins.model.Jenkins.instance.getItem("pipeline.preview.build")
    def build = job.getBuildByNumber(buildNumber)
    def art = build.artifacts[0]
    return art.file
}

并将此函数作为您的阶段步骤之一。
