获取Jenkins多分支管道中的分支列表 [英] Get list of branches in Jenkins multibranch pipeline

本文介绍了获取Jenkins多分支管道中的分支列表的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

Jenkins多分支管道项目的Blue Ocean界面显示了几个自动创建的分支.

The Blue Ocean interface to a Jenkins multibranch pipeline project shows several branches that were automatically created.

有没有一种编程方式来列出要添加到Jenkinsfile中的代码中管道中的分支?

Is there a programmatic way to list the branches in the pipeline from code to be added to a Jenkinsfile?

此问题询问位于Jenkins应用程序对象模型内的Jenkins Project分支信息，应通过Jenkins API或CLI进行访问.

This question asks about Jenkins Project branch information located inside the Jenkins application object model, which should be accessible via the Jenkins API or CLI.

我查看了http://<jenkins-home>/env-vars.html/上所有可用的变量，但这些变量似乎都没有描述我所寻找的信息.

I looked at all the variables that are available at http://<jenkins-home>/env-vars.html/ , but none of those variables seem to describe the information that I seek.

Multibranch项目显然可以使用项目分支列表.为了将分支列表提取到在Jenkinsfile中运行的脚本中，需要什么语法?

The list of project branches is clearly available to the Multibranch project. What syntax is required in order for the list of branches to be extracted into a script that runs in a Jenkinsfile?

我尝试了@bto的建议，但是却收到一条错误消息，指示已找到意外的(.

I tried @bto's suggestion, but I am getting an error indicating that an unexpected ( has been found.

以下是产生新错误的相关最小Jenkinsfile:

Here is the relevant minimal Jenkinsfile that produces the new error: 

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:

And here is the log file containing the error: 

 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，我根据@bto的注释删除了封闭的sh """ ... """块，但这产生了关于No Steps的不同错误.

Alternatively, I removed the enclosing sh """ ... """ block, per @bto's comment, but this produced a different error about No Steps.

混淆可能是由于这是脚本管道"而不是声明管道".在此链接中查看>声明性"管道与脚本管道之间的区别.

The confusion may be due to this being a 'scripted pipeline' and not a 'declarative pipeline'. See the difference between 'declarative' and scripted pipelines 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
    }
}

这是另一种方法产生的日志:

And here is the log that results from the alternative approach:

隔离错误:

如果将@bto的建议代码减少到以下三行，则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()，如下所示:

If I reduce @bto's suggested code to the following three lines, I can then turn the error off by commenting out the second of the following three lines, and then turn the error back on again by uncommenting the second line. Therefore, the line of code that causes the Java.ip.NonSerializableException is project.getItems(), as follows: 

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.

Note that I also needed to add project = null.

问题添加例外:

当我尝试部署@bto的建议Jenkinsfile时，Jenkins Blue Ocean界面中显示以下错误:

When I try to deploy @bto's suggested Jenkinsfile, the following error is shown in the Jenkins Blue Ocean interface:

但是，当我在错误消息上的任何位置单击时，什么也没有发生.

But nothing happens when I click in any location on the error message.

然后，我打开一个单独的窗口来访问Jenkins工具以添加安全例外，但是没有任何东西排队等待自动批准，也没有任何东西允许我手动输入需要批准的命令.我得到的是以下屏幕:

Then I open a separate window to access the Jenkins tool for adding security exceptions, but nothing is queued up for automatic approval, and nothing allows me to manually enter the commands that need to be approved. What I get is the following screen:

向下滚动到图像中显示的屏幕底部不会显示任何新内容.

Scrolling down to the bottom of the screen shown in the image does not reveal anything new.

另一种将白名单加入的尝试:

根据@bto的评论，我进入http://<jenkins-home>/script并输入以下内容，然后单击 Run (运行)按钮:

Per @bto's comment, I went to http://<jenkins-home>/script and entered the following, and then clicked the Run button: 

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http://<jenkins-home>/scriptApproval处的NOTHING已添加到批准队列:

But the following error was generated, and NOTHING was added to the approval queue at http://<jenkins-home>/scriptApproval:

要解决此错误，还必须更改什么?

What else must be changed in order to resolve this error?

推荐答案

您需要将很多方法签名列入白名单*才能使它起作用，但是您应该能够执行以下操作:

You're going to need to whitelist* a lot of method signatures to get this to work, but you should be able to do something like:

@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，此代码段从原始请求中排除了try/catch错误处理:通过捕获白名单异常，它们没有正确添加到scriptApproval列表中. 完成后，没有白名单异常，您可以重新添加错误处理，如下所示:

Note that this snippet excludes the try/catch error handling from the original request: By catching the whitelist exceptions, they aren't correctly added to the scriptApproval list. After it makes it through with no whitelist exceptions, you can add the error handling back in, as follows: 

@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()
    try {
        stage ('Clone') {
            getBranchNames(jenkins.model.Jenkins.instance.getItem(env.JOB_NAME.minus("/${env.JOB_BASE_NAME}")))
            echo "done reading jobs"
        }
    } catch (err) {
        error "BUILD FAILED: ${err}"
    }
}

*白名单通过http://<jenkins-home>/scriptApproval进行.我基本上运行了测试工作，查看了控制台输出故障，单击了批准链接，然后批准"了有问题的项目.我必须将以下内容列入白名单才能使其正常工作:

* Whitelisting happens through http://<jenkins-home>/scriptApproval. I basically ran my test job, looked at the console output failure, clicked the approval link, and "approved" the item in question. I had to whitelist the following to get this to work:

  • staticMethod jenkins.model.Jenkins getInstance'
    • 注意！该漏洞被标记为潜在的安全漏洞(因为它允许脚本使用Jenkins实例)
