在 Jenkins 流水线作业中访问 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:

Started by user anonymous
[Pipeline] Allocate node : Start
Running on master in /var/lib/jenkins/jobs/test/workspace
[Pipeline] node {
[Pipeline] git

[Pipeline] } //node

未填充环境变量 env.GIT_COMMIT、env.GIT_BRANCH.这些值是否在其他变量中可用?

The env variables env.GIT_COMMIT, env.GIT_BRANCH are not populated. Are those values available in another variables?

推荐答案

这里是一个如何获取 GIT_COMMIT 的例子(参考:Jenkins GitHub):

Here is an example of how you can get GIT_COMMIT (ref: Jenkins GitHub):

// These should all be performed at the point where you've
// checked out your sources on the agent. A 'git' executable
// must be available.
// Most typical, if you're not cloning into a sub directory
shortCommit = sh(returnStdout: true, script: "git log -n 1 --pretty=format:'%h'").trim()

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 变量的功能，也许您可​​以发送拉取请求.

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.
