Jenkins Pipeline 抛出 java.io.NotSerializableException: org.jenkinsci.plugins.workflow.job.WorkflowRun 即使使用@NonCPS [英] Jenkins Pipeline throwing java.io.NotSerializableException: org.jenkinsci.plugins.workflow.job.WorkflowRun even with @NonCPS

问题描述

代码相当简单，我只想要一个发布到 slack 的 rev-list.但是导致我出现问题的部分是当我实际上试图从 git 获取 rev-list 时.

问题代码

@NonCPSdef getRevisionList(currentCommit, lastSuccessfulCommit) {def 提交 = sh(脚本:git rev-list $currentCommit $lastSuccessfulCommit"，返回标准输出:真).split('
')回声$提交"}

完整代码:

詹金斯给我的错误是这样的:

原因:java.io.NotSerializableException: org.jenkinsci.plugins.workflow.job.WorkflowRun

我正在关注以下内容，但我收到了错误消息.我已经尝试以原始方式运行它，但也没有任何运气.

Jenkinsfile - 获取构建之间的所有更改

解决方案

你看到的异常是由下面这行引起的:

def currentBuild = currentBuild.rawBuild

currentBuild.rawBuild 返回一个不可序列化的对象，因此必须在 @NonCPS 方法内调用以避免出现此异常.尝试简化您的辅助方法，以便它们访问 @NonCPS 内的 currentBuild 变量:

@NonCPSdef getRevisionList(currentCommit, lastSuccessfulCommit) {def 提交 = sh(脚本:git rev-list $currentCommit $lastSuccessfulCommit"，返回标准输出:真).split('
')回声$提交"}@NonCPSdef getLastSuccessfulCommit() {def lastSuccessfulHash = nulldef lastSuccessfulBuild = currentBuild.rawBuild.getPreviousSuccessfulBuild()if ( lastSuccessfulBuild ) {lastSuccessfulHash = commitHashForBuild(lastSuccessfulBuild)}返回最后一个成功的哈希}@NonCPSdef commitHashForBuild() {def scmAction = currentBuild?.rawBuild?.actions?.find { action ->动作实例 jenkins.scm.api.SCMRevisionAction }返回 scmAction?.revision?.hash}

currentBuild.rawBuild - 带有 其他 API，仅适用于沙盒外的受信任库或管理员批准的脚本；该值不会是 Serializable 因此您只能在标记为 @NonCPS

的方法中访问它<小时>

The code is fairly simple I just want a rev-list to post to slack. But the part that is causing me the issue is when I am actually trying to get the rev-list from git.

Problem Code

@NonCPS
def getRevisionList(currentCommit, lastSuccessfulCommit) {
     def commits = sh(
        script: "git rev-list $currentCommit $lastSuccessfulCommit",
        returnStdout: true
    ).split('
')
    echo "$commits"
}

Complete Code:

pipeline {
    environment {
      failureMessage = ""
    }

  agent {
        node {
            label 'gsacsp-build02.reisys.com'
        }
    }
    stages {
        stage('Parse Commits') {
            steps {
                script {
                    def currentBuild = currentBuild.rawBuild
                    def currentCommit = commitHashForBuild(currentBuild)
                    def lastSuccessfulCommit =  getLastSuccessfulCommit()

                    getRevisionList(currentCommit, lastSuccessfulCommit)
                }
            }
        }
    }
    post {
        always {
            withCredentials([string(credentialsId: 'BOT_SLACK_HOOK', variable: 'BOT_SLACK_HOOK')]) {
               script {
                    failureMessage = readFile "jenkinshelpers/slackfailuremessage.json"
                    sh "curl -X POST -H 'Content-type: application/json' --data '$failureMessage' $BOT_SLACK_HOOK"
                }
            }
        }
    }
}

//Groovy Helper Methods

@NonCPS
def getRevisionList(currentCommit, lastSuccessfulCommit) {
     def commits = sh(
        script: "git rev-list $currentCommit $lastSuccessfulCommit",
        returnStdout: true
    ).split('
')
    echo "$commits"
}

@NonCPS
def getLastSuccessfulCommit() {
  def lastSuccessfulHash = null
  def lastSuccessfulBuild = currentBuild.rawBuild.getPreviousSuccessfulBuild()
  if ( lastSuccessfulBuild ) {
    lastSuccessfulHash = commitHashForBuild( lastSuccessfulBuild )
  }
  return lastSuccessfulHash
}

@NonCPS
def commitHashForBuild(build) {
    def scmAction = build?.actions.find { action -> action instanceof jenkins.scm.api.SCMRevisionAction }
    return scmAction?.revision?.hash
}

The Error Jenkins is giving me is this:

an exception which occurred:

Caused: java.io.NotSerializableException: org.jenkinsci.plugins.workflow.job.WorkflowRun

More of less I am following the below, however I am getting the error. I have tried running it the original way but am not having any luck with that either.

Jenkinsfile - get all changes between builds

解决方案

The exception you see is caused by the following line:

def currentBuild = currentBuild.rawBuild

currentBuild.rawBuild returns a non-serializable object, thus has to be called inside a @NonCPS method to avoid getting this exception. Try simplifying your helper methods so they access currentBuild variable inside @NonCPS:

@NonCPS
def getRevisionList(currentCommit, lastSuccessfulCommit) {
     def commits = sh(
        script: "git rev-list $currentCommit $lastSuccessfulCommit",
        returnStdout: true
    ).split('
')
    echo "$commits"
}

@NonCPS
def getLastSuccessfulCommit() {
  def lastSuccessfulHash = null
  def lastSuccessfulBuild = currentBuild.rawBuild.getPreviousSuccessfulBuild()
  if ( lastSuccessfulBuild ) {
    lastSuccessfulHash = commitHashForBuild( lastSuccessfulBuild )
  }
  return lastSuccessfulHash
}

@NonCPS
def commitHashForBuild() {
    def scmAction = currentBuild?.rawBuild?.actions?.find { action -> action instanceof jenkins.scm.api.SCMRevisionAction }
    return scmAction?.revision?.hash
}

currentBuild.rawBuild - a hudson.model.Run with further APIs, only for trusted libraries or administrator-approved scripts outside the sandbox; the value will not be Serializable so you may only access it inside a method marked @NonCPS
