[英]How to add environment variables from the Code in Jenkins?
So basically the program requires an env variable which is read this way:所以基本上程序需要一个以这种方式读取的环境变量:
var a = java.lang.System.getenv('envVariable');
Now as I am using a Jenkins Pipeline, I was looking for a way to supply this env variable in the pipeline, but I didn't find a way.现在,当我使用 Jenkins 管道时,我正在寻找一种在管道中提供此环境变量的方法,但我没有找到方法。 Is there a way to achieve this with Jenkins?
有没有办法通过 Jenkins 实现这一目标?
You should use the environment
section to define environment variables.您应该使用
environment
部分来定义环境变量。 The scope depends on the level of environment
. scope 取决于
environment
等级。 Please see the official documentation for further details: https://www.jenkins.io/doc/book/pipeline/jenkinsfile/#using-environment-variables更多详情请查看官方文档: https://www.jenkins.io/doc/book/pipeline/jenkinsfile/#using-environment-variables
Example:例子:
pipeline {
agent {
label 'my_label'
}
// These are visible in all stages
environment {
MY_ENV_VAR = 'value_of_var'
DEBUG = 'true'
}
stages {
stage('Build') {
// These are visible only in the current stage (Build)
environment {
STAGE_ENV = 'value_stage_env'
}
steps {
echo "MY_ENV_VAR = ${MY_ENV_VAR}"
echo "DEBUG = ${DEBUG}"
echo "STAGE_ENV = ${STAGE_ENV}"
sh 'printenv'
}
}
}
}
