jenkins - 获取 Jenkins 多分支管道中的分支列表

Question

Jenkins 多分支管道项目的 Blue Ocean 界面显示了自动创建的多个分支。

是否有一种编程方式可以从要添加到 Jenkinsfile 的代码中列出管道中的分支？

此问题询问位于 Jenkins 应用程序对象模型内的 Jenkins 项目分支信息，该信息应可通过 Jenkins API 或 CLI 访问。

我查看了 http://<jenkins-home>/env-vars.html/ 中可用的所有变量，但这些变量似乎都无法描述我所寻求的信息。

项目分支列表对于多分支项目显然是可用的。需要什么语法才能将分支列表提取到在 Jenkinsfile 中运行的脚本中？

@bto 的建议

我试过@bto的建议，但我收到一条错误，表明意外的 (已被发现。

这是相关的最小值 Jenkinsfile产生新的错误:

node {
    // Clean workspace before doing anything
    deleteDir()

    try {
        stage ('Clone') {
            sh '''
                project = jenkins.model.Jenkins.instance.getItem(env.JOB_NAME.minus("/${env.JOB_BASE_NAME}"))
                    project.getItems().each { job ->
                        println job.getProperty(org.jenkinsci.plugins.workflow.multibranch.BranchJobProperty.class).getBranch().getName()
                    }
            '''
        }
    } catch (err) {
        currentBuild.result = 'FAILED'
        throw err
    }
}

这是包含错误的日志文件:

 project = jenkins.model.Jenkins.instance.getItem(env.JOB_NAME.minus("/${env.JOB_BASE_NAME}")) project.getItems().each { job -> println job.getProperty(org.jenkinsci.plugins.workflow.multibranch.BranchJobProperty.class).getBranch().getName() }— Shell Script<1s
    [ne_GWS-43-getissueforcommit-M2X23QGNMETLDZWFK7IXVZQRCNSWYNTDFJZU54VP7DMIOD6Z4DGA] Running shell script

    script returned exit code 2

第二种方法

或者，我删除了封闭的 sh """ ... """ block ，每@bto的评论，但这产生了关于 No Steps 的不同错误.

造成混淆的原因可能是这是“脚本化管道”而不是“声明性管道”。查看“声明式”管道和脚本化管道之间的区别 at this link .

这是替代的最小 Jenkinsfile 。

node {
    // Clean workspace before doing anything
    deleteDir()

    try {
        stage ('Clone') {
            project = jenkins.model.Jenkins.instance.getItem(env.JOB_NAME.minus("/${env.JOB_BASE_NAME}"))
                project.getItems().each { job ->
                    println job.getProperty(org.jenkinsci.plugins.workflow.multibranch.BranchJobProperty.class).getBranch().getName()
                }
        }
    } catch (err) {
        currentBuild.result = 'FAILED'
        throw err
    }
}

这是替代方法产生的日志:

隔离错误:

如果我减少@bto将建议的代码添加到以下三行，然后我可以通过注释掉以下三行中的第二行来关闭错误，然后通过取消注释第二行来再次打开错误。因此，导致 Java.ip.NonSerializableException 的代码行是 project.getItems() ，如下:

project = jenkins.model.Jenkins.instance.getItem(env.JOB_NAME.minus("/${env.JOB_BASE_NAME}"))
//project.getItems()
project = null 

请注意，我还需要添加 project = null 。

添加异常(exception)时出现问题:

当我尝试部署@bto时建议Jenkinsfile ，Jenkins Blue Ocean界面出现如下错误:

但是当我单击错误消息上的任何位置时，没有任何反应。

然后我打开一个单独的窗口来访问用于添加安全异常(exception)的 Jenkins 工具，但没有任何内容排队等待自动批准，也没有任何内容允许我手动输入需要批准的命令。我得到的是以下屏幕:

向下滚动到图像中显示的屏幕底部不会显示任何新内容。

再次尝试加入白名单:

每@bto的评论，我去了http://<jenkins-home>/script并输入以下内容，然后单击运行按钮:

def getBranchNames(project){
    project.getItems().each { job ->
        echo job.getProperty(org.jenkinsci.plugins.workflow.multibranch.BranchJobProperty.class).getBranch().getName()
    }
}
getBranchNames(jenkins.model.Jenkins.instance.getItem("my-project-name-string"))

但是生成了以下错误，并且没有任何内容添加到 http://<jenkins-home>/scriptApproval 的批准队列中:

为了解决此错误还必须更改哪些内容？

Answer 1

您将需要将许多方法签名列入白名单*才能使其正常工作，但您应该能够执行以下操作:

@NonCPS
def getBranchNames(project){
    project.getItems().each { job ->
        echo job.getProperty(org.jenkinsci.plugins.workflow.multibranch.BranchJobProperty.class).getBranch().getName()
    }
}

node {
    // Clean workspace before doing anything
    deleteDir()
    stage ('Clone') {
        getBranchNames(jenkins.model.Jenkins.instance.getItem(env.JOB_NAME.minus("/${env.JOB_BASE_NAME}")))
        echo "done reading jobs"
    }
}

请注意，此代码段不包括 try/catch原始请求的错误处理:通过捕获白名单异常，它们不会正确添加到 scriptApproval 列表中。 在它通过并且没有白名单异常的情况下，您可以重新添加错误处理，如下所示:

@NonCPS
def getBranchNames(project){
    project.getItems().each { job ->
