没有BASH的Jenkins Pipeline Step withEnv无法正常工作 [英] Jenkins Pipeline Step withEnv does not work without BASH

问题描述

我无法在Jenkins管道中为容器设置环境变量. 看来，"withEnv"在没有bash的机器上不能很好地工作.

I've trouble setting an environment variable for a container in an Jenkins pipeline. It seems, that "withEnv" does not work nicely with machines without bash.

您可以确认吗?我找不到官方声明；-)

Can you confirm that? I cannot find an official statement ;-)

当我在Jenkins从站上运行以下代码片段时，它可以工作. 但是，在没有BASH的docker容器中执行该命令时，未设置"$ test".

When I run the following snippet on the Jenkins slave it works. But when it is executed in a docker container without BASH "$test" isn't set.

 withEnv(["test='asd'"]){
      sh 'echo $test'
 }

推荐答案

如果我没记错的话，我认为该变量设置不正确.

If I'm not mistaken, I believe the variable is not set correctly.

尝试一下:

withEnv(["test=asd"]){
      sh "echo \$test"
 }

在Jenkins管道中:

Within a Jenkins pipeline:

$var = Groovy parameter
\$var (within a sh closure) = Bash parameter
${var} = also refers to Groovy parameter

要将groovy变量插入bash变量中:

In order to insert a groovy variable into a bash variable:

sh ("VAR=${GROOVY_VAR}")

在sh闭包内使用bash变量:

Using a bash variable inside a sh closure:

sh (" echo \$BASH_VAR")
