如何使用 Jenkinsfile 在 groovy 函数中使用环境变量 [英] How to use environment variables in a groovy function using a Jenkinsfile

问题描述

我正在尝试使用在 Jenkinsfile 中的任何节点之外定义的环境变量.我可以在任何节点的任何管道步骤中将它们纳入范围，但不能在函数内部.我现在能想到的唯一解决方案是将它们作为参数传递.但我想直接在函数内部引用环境变量，这样我就不必传入这么多参数.这是我的代码.如何让函数输出正确的 BRANCH_TEST 值?

I'm trying to use environment variables defined outside any node in a Jenkinsfile. I can bring them in scope on any pipeline step in any node but not inside of a function. The only solution I can think of for now is to pass them in as parameters. But I would like to reference the env variables directly inside the function so I don't have to pass so many parameters in. Here is my code. How can I get the function to output the correct value of BRANCH_TEST?

def BRANCH_TEST = "master"

node {
    deploy()
}

def deploy(){
    echo BRANCH_TEST
}

Jenkins 控制台输出:

Jenkins console output:

[Pipeline]
[Pipeline] echo
null
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS

推荐答案

解决方案是

1. 使用@Field注解

从声明中删除 def.有关使用 def 的说明，请参阅 Ted 的回答.

Remove def from declaration. See Ted's answer for an explanation on using def.

解决方案 1(使用 @Field)

Solution 1 (using @Field)

import groovy.transform.Field

@Field def BRANCH_TEST = "master"

   node {
       deploy()
   }

   def deploy(){
       echo BRANCH_TEST
   }

解决方案 2(删除 def)

Solution 2 (removing def)

BRANCH_TEST = "master"

   node {
       deploy()
   }

   def deploy(){
       echo BRANCH_TEST
   }
