Question

运行JavaGroovy脚本并更新到最新的Groovy管道时。谢谢你的帮助。

我得到了一个异常：在对象组织中的字段线程中的字段程序中的字段e中的字段调用者中的字段内局部变量。詹金西。插件。工作流程。cps。CpsThreadGroup@3123aac2原因：java。木卫一。NotSerializableException:hudson。模型运行$Artifact我认为问题的代码是

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（）存储包括：“输出/**”，名称：“包”

根据这篇文章,，https://github.com/jenkinsci/pipeline-plugin/blob/master/TUTORIAL.md#serializing-我尝试使用的局部变量

@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' 
                        }

Answer 1

根据这篇文章：最安全的方法是在标有注释@NonCPS的方法中隔离非序列化状态的使用

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
}

并将此函数作为阶段步骤之一调用。
