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.我可以将它们置于任何节点中任何管道步骤上的作用域中，但不能置于函数内部.我现在唯一想到的解决方案是将它们作为参数传递.但是我想直接在函数内部引用env变量，因此不必传入太多参数.这是我的代码.如何获得输出正确的 BRANCH_TEST 值的函数?

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

1. 使用 @Field 注释

从声明中删除def.有关使用def的说明，请参见 Ted的答案.

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

解决方案1(使用 @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
   }
