git - 在 Jenkinsfile 中隔离存储库分支的名称

问题描述

Jenkinsfile为了将提交的分支名称隔离到可以在日志中打印出来的变量中，需要对以下内容进行哪些具体更改？ 在下面的例子中，分支的名称是GWS-43-getissueforcommit。

以下是具体情况：

詹金斯文件：

以下代码Jenkinsfile在运行命令产生的输出中间打印出分支名称checkout(scm).GIT_ASKPASS，但是当后续代码行 ( sh "echo 'The repo Ask Pass is: ${repoAskPass}'") 尝试打印出命令的封装结果时，此信息会丢失： 

node {
    // Clean workspace before doing anything
    deleteDir()
    try {
        stage ('Clone') {
            def repoAskPass = checkout(scm).GIT_ASKPASS
            sh "echo 'The repo Ask Pass is: ${repoAskPass}'"
        }
    } catch (err) {
        currentBuild.result = 'FAILED'
        throw err
    }
}

结果日志：

结果日志输出为：

重述问题：

上面的 Jenkinsfile 需要如何修改才能在日志中输出以下行： 

The name of the branch containing the commit for this build is: 
GWS-43-getissueforcommit

标签： gitjenkinscontinuous-integrationjenkins-pipeline

解决方案

GIT_ASKPASS用于获取用户凭据 - 它与分支无关。

这是插件集的变量列表，您可以使用它们。从这里您可以看到它GIT_BRANCH为您提供了远程分支并GIT_LOCAL_BRANCH为您提供了已签出的本地分支。

def branch = checkout(scm).GIT_BRANCH
sh "echo 'The name of the branch containing the commit for this build is: ${branch}'"

这将打印远程分支名称以及原始前缀（通常是可取的）。但是如果你想要它没有前缀：

def branch = checkout(scm).GIT_BRANCH
branch = branch.substring(branch.indexOf('/') + 1)
sh "echo 'The name of the branch containing the commit for this build is: ${branch}'"
