Question

当我从构建页面单击“重建”时，jenkins将重建并运行新作业-具有新jenkins内部编号的新作业。

如何获取执行重建的作业的内部版本号？

我不是在谈论以前的内部版本号。

对构建10说我，我进入构建5，然后单击“重建”。我如何像在env.BUILD_NUMBER中那样从管道内部那个构建编号（5）？

我假设您正在使用Groovy Pipeline，并且已经知道全局变量（请参阅全局变量参考）。

currentBuild变量具有字段rawBuild，该字段返回hudson.model.Run对象
调用rawBuildObject#getCauses()或rawBuildObject#getCauses()并返回一些Cause对象。

以下脚本：

node {
    stage('test advance script') {
            echo "current build number: ${currentBuild.number}"
            echo "previous build number: ${currentBuild.previousBuild.getNumber()}"
            def causes = currentBuild.rawBuild.getCauses()
            echo "causes: ${causes}"
            def rebuildCause0 = currentBuild.rawBuild.getCause(com.sonyericsson.rebuild.RebuildCause)
            echo "rebuildCause0: ${rebuildCause0}"
            echo "rebuild up number: ${rebuildCause0.getUpstreamBuild()}"
        }
}

但是正如我们在聊天中讨论的那样，Rebuilder插件以错误的方式使用CauseAction。如果将其固定为this，则控制台输出应为：

current build number: 72
previous build number: 71
causes: [hudson.model.Cause$UserIdCause@679c1066, job/DMP/job/test-pipeline/63[hudson.model.Cause$UserIdCause@679c1066]]
rebuildCause0: job/DMP/job/test-pipeline/63[hudson.model.Cause$UserIdCause@679c1066]
rebuild up number: 63

看到以下错误时，请记住scriptApproval：

Scripts not permitted to use method hudson.model.Run getCauses. Administrators can decide whether to approve or reject this signature.

假设您可以卷曲自己的 jenkins 构建：

def getOriginalRebuildNum(String jobUrl = "${JOB_URL}"){
    def urlJsonPath
    def buildNumber
    def result
    ansiColor('xterm') {
        try {
            buildNumber = "${BUILD_NUMBER}"
            urlJsonPath = "${JOB_URL}/${buildNumber}/api/json"
            while (!buildNumber.isEmpty()) {
                result = buildNumber
                buildNumber = sh(
                        script:
                                """
                            curl -s $urlJsonPath \
                                | jq -r '.actions[] 
                                | select(."_class" == "hudson.model.CauseAction") .causes[] 
                                | select(.upstreamBuild != null).upstreamBuild'
                                """,
                        returnStdout: true).trim()
                urlJsonPath = "${JOB_URL}/${buildNumber}/api/json"
            }
            echo "Original Build: ${JOB_URL}/${result}/"
        }
        catch (err) {
            "Error: Could not retrieve original Build Number from ${urlJsonPath} - $err"
            result = "${BUILD_NUMBER}"
        }
    }
    return result
}

如何从执行重建的位置获取内部版本号？
