Jenkins中使用环境变量

直接使用环境变量

groovy 复制代码

pipeline {
    agent {
        label "${28}"
    }

    stages {
        
        stage("git clone"){
            steps{
                script{
                    sh """
                        pwd
                        ls
                    """
                  
                    // 环境变量的使用
                    // 输出所有环境变量  
                    echo "All environment variables: ${env}"  
                    
                    // 输出单个环境变量的值  
                    echo "HOME directory: ${env.HOME}"  
                    echo "Jenkins user: ${env.USER}"  
                    echo "Jenkins WORKSPACE: ${env.WORKSPACE}"
                    
                    // 遍历输出所有的环境变量  
                    env.each { key, value ->  
                        echo "Environment variable $key: $value"  
                    }
                    
                    // 如下为/home/jenkins/program/jenkins/workspace/middle_nMedia_test
                    echo "${WORKSPACE}"
                    // 构建号
                    echo "${BUILD_NUMBER}"
                    echo "${WORKSPACE}/${BUILD_NUMBER}"
                }
            }
        }
    }
}

Console Output:

通过environment间接使用

在environment中定义新的全局的环境变量，在后文中使用。

亦可以将参数化构建的参数在environment中赋值给新的环境变量，然后后文中同样可以使用。

groovy 复制代码

pipeline {
    agent {
        label "28"
    }
    
    environment {
        // 通过环境变量定义新的变量
        work_dir = "${BUILD_NUMBER}"
        server_main_workspace = "${WORKSPACE}/${BUILD_NUMBER}"

    }

    stages {
        stage("git clone"){
            steps{
                script{
                    sh """
                        pwd
                        ls
                    """
                    
                    echo "${work_dir}"
                    echo "${server_main_workspace}"
                }
            }
        }
    }
}
