在Jenkins管道作业上访问SCM（Git）变量 [英] Accessing SCM (Git) variables on a Jenkins Pipeline job

问题描述

这是我的管道代码：

  node（'master'）{
 git url：$ GIT_REPO_URL ，branch：$ GIT_BRANCH
 echo env.GIT_COMMIT 
 echo env.GIT_BRANCH 
 echo env.GIT_REVISION 
} 
  

构建结果如下所示：

 由用户anonymous 
 [Pipeline]分配节点：启动
在/ var / lib / jenkins / jobs / test / workspace中的master上运行
 [Pipeline]节点{
 [Pipeline] git 
> git rev-parse --is-inside-work-tree＃timeout = 10 
从远程Git仓库获取更改
> git config remote.origin.url https：//acme/scm/app.git＃timeout = 10 
从https：//acme/scm/app.git获取上游更改
> git --version＃timeout = 10 
> git fetch --tags --progress https：//acme/scm/app.git + refs / heads / *：refs / remotes / origin / *

> git rev-parse refs / remotes / origin / origin / master ^ {commit}＃timeout = 10

未填充env变量env.GIT_COMMIT，env.GIT_BRANCH。这些值是否可用于其他变量？
解决方案
以下示例显示如何获取GIT_COMMIT  -   https://github.com/jenkinsci/pipeline-examples/blob/master /pipeline-examples/gitcommit/gitcommit.groovy  
 
 
 
您也可以扩展它以公开GIT_BRANCH。该脚本来自cloudbees管理的工作流示例git repo。如果您添加检索GIT_BRANCH变量的能力，也许您可​​以发送拉取请求。
 
Here's my pipeline code:
node ('master') {
    git url: "$GIT_REPO_URL", branch: "$GIT_BRANCH"
    echo env.GIT_COMMIT
    echo env.GIT_BRANCH
    echo env.GIT_REVISION
}
The build results looks like:

[Pipeline] } //node

[Pipeline] End of Pipeline
Finished: SUCCESS
The env variables env.GIT_COMMIT, env.GIT_BRANCH are not populated. Are those values available in another variables?
解决方案
Here is an example of how you can get GIT_COMMIT - https://github.com/jenkinsci/pipeline-examples/blob/master/pipeline-examples/gitcommit/gitcommit.groovy

You can extend it to expose GIT_BRANCH as well.  This script is from the workflow examples git repo managed by cloudbees. Maybe you can send a pull request if you add capability to retrieve GIT_BRANCH variable.
