出口指令在詹金斯管道 [英] Export command in Jenkins pipeline

问题描述

如何在Jenkins管道中添加exportunix命令？
我有一个詹金斯的舞台和'台阶'。导出命令的语法是什么我需要使用export命令设置环境变量'PATH'。

解决方案

您可以像这样更新 $ PATH >

  pipeline {
 agent {label'docker'} 
 stages {
 stage（'build'） {
 steps {
 
 // JENKINSHOME只是一个名字来帮助可读性
 withEnv（['PATH + JENKINSHOME = / home / jenkins / bin']）{
 echoPATH is：$ PATH
} 
} 
} 
} 
} 
  

当我运行这个结果是：

  [管道] echo 
 PATH是：/ home / jenkins / bin：/ usr / local / sbin：/ usr / local / bin：/ usr / sbin：/ usr / bin：/ sbin：/ bin：/ usr / games：/ usr / local / games 
  

这是什么？ PATH + JENKINSHOME 语法？从在designhammer.com的博客引用：

这样：

  / my / additional / path：$ PATH 
  

表示为：

  PATH + ANYSTRING = /我/额外/路径。 
  

ANYSTRING 只是一个名字来帮助可读性。如果它不能帮助可读性，在你看来，你可以省略它。所以这是相当的：

  PATH + = / my / additional / path 
  pre> 
 
 
以上（ withEnv ）允许您更新$ $ $ $ $ $ $ $ $ $ $ code>为管道的特定部分。要更新整个管道的 $ PATH ，您不能使用 PATH + ANYSTRING 语法，但这可以：
  pipeline {
 agent {label'docker'} 
 environment {
 PATH = / hot / new / bin：$ PATH
} 
阶段{
 stage（'build'）{
 steps {
 echoPATH is：$ PATH 
} 
} 
} 
} 
  
生成输出：
  [Pipeline] echo 
 PATH是：/ hot / new / bin：/ usr / local / sbin：/ usr / local / bin：/ usr / sbin：/ usr / bin：/ sbin：/ bin：/ usr / games：/ usr / local / games 
  
 
How to add an 'export' unix command in a Jenkins pipeline?
I have a Jenkins 'stage' and 'steps' within it. What is the syntax for an export command. I need to set the environment variable 'PATH' using the export command. 
解决方案
You can update the $PATH like this:
pipeline {
  agent { label 'docker' }
  stages {
    stage ('build') {
      steps {

        // JENKINSHOME is just a name to help readability
        withEnv(['PATH+JENKINSHOME=/home/jenkins/bin']) {
          echo "PATH is: $PATH"
        }
      }
    }
  }
}
When I run this the result is:
[Pipeline] echo
PATH is: /home/jenkins/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
What the heck is this PATH+JENKINSHOME syntax? Quoting from a blog at designhammer.com:

This:
/my/additional/path:$PATH
is expressed as:
PATH+ANYSTRING=/my/additional/path.
ANYSTRING is just a name to help readability. If it doesn't help readability, in your view, you can omit it. So this is equivalent:
PATH+=/my/additional/path
The above (withEnv) allows you to update the $PATH for a specific part of your pipeline. To update the $PATH for the entire pipeline, you can't use the PATH+ANYSTRING syntax, but this works:
pipeline {
  agent { label 'docker' }
  environment {
    PATH = "/hot/new/bin:$PATH"
  }
  stages {
    stage ('build') {
      steps {
        echo "PATH is: $PATH"
      }
    }
  }
}
Produces output:
[Pipeline] echo
PATH is: /hot/new/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
