Jenkins 管道抛出 java.io.NotSerializableException: org.jenkinsci.plugins.workflow.job.WorkflowRun 即使使用 @NonCPS

Question

代码相当简单，我只想要一个 rev-list 发布到 slack。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

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

完整代码：

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

詹金斯给我的错误是这样的：

an exception which occurred:
in field com.cloudbees.groovy.cps.impl.BlockScopeEnv.locals

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

更多或更少我正在关注以下内容，但是我收到了错误。我曾尝试以原始方式运行它，但也没有任何运气。

您看到的异常是由以下行引起的：

def currentBuild = currentBuild.rawBuild

currentBuild.rawBuild返回一个不可序列化的对象，因此必须在@NonCPS方法内部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currentBuild内部变量@NonCPS：

@NonCPS
def getRevisionList(currentCommit, lastSuccessfulCommit) {
     def commits = sh(
        script: "git rev-list $currentCommit $lastSuccessfulCommit",
        returnStdout: true
    ).split('\n')
    echo "$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 -hudson.model.Run带有更多 API 的，仅适用于沙箱外的受信任库或管理员批准的脚本；该值不会是，Serializable因此您只能在标记的方法中访问它@NonCPS
