Jenkins环境变量与构建工具 (pipeline)

标签：10.0 pipeline git http Pipeline world Jenkins 环境变量

Jenkins内置变量

pipeline {
    agent any
    stages {
        stage ('mcwtest') {
            steps {
                echo "Running ${env.BUILD_NUMBER} on ${env.JENKINS_URL}" // 方法一
                echo "Running $env.BUILD_NUMBER on $env.JENKINS_URL" // 方法二
                echo "Running ${BUILD_NUMBER} on ${JENKINS_URL}" // 方法三
                echo "========>printenv:"
                sh "printenv"
            }
        }
    }
}

可以看到三种方式都获取到了内置变量

我们看下打印的所有内置变量

自定义pipeline环境变量

日常

pipeline {
    agent any
    environment {
        CC = 'python'
    }
    stages {
        stage ('mcwtest') {
            environment {
                DEBUG_FLAGS = '-V'
            }
            steps {
                echo "${CC}"
                echo "${DEBUG_FLAGS}"
                sh "${CC} ${DEBUG_FLAGS}"
                echo "========>printenv:"
                sh "printenv"
            }
        }
    }
}

没有clang命令，所以执行失败，pipeline失败了，后面的打印环境变量也没执行

比如修改为python -V

都往下执行了

查看自定义的环境变量

一个环境变量引用另一个环境变量

pipeline {
    agent any
    environment {
        __server_name = 'mail-server'
        __virsion = "$BUILD_NUMBER"
        __artifact_name = "${__server_name}-${__virsion}.jar"
    }
    stages {
        stage ('mcwtest') {
            environment {
                DEBUG_FLAGS = '-V'
            }
            steps {
                echo "${__server_name}"
                echo "${__artifact_name}"
            }
        }
    }
}
