Jenkins 看不到 GIT 环境变量

Question

我和Jenkins一起使用Git插件。

我尝试访问$GIT_BRANCH环境变量，我得到了null。然后，当我使用Groovy脚本打印环境变量时，我发现没有Git环境变量：

为了执行Jenkins脚本，我使用了Groovy插件，包括前一步“执行系统Groovy脚本”和以下代码:

import hudson.model.*

def env = System.getenv()

println "env is: " + env

为什么我看不到任何GIT环境变量？

Answer 1

这将包含“GIT_BRANCH”

def branch = build.getEnvVars()["GIT_BRANCH"]
println "branch is: " + branch
