### 前提：jenkins和相关软件已经部署完成 ###

### 实验环境： ###

名称          版本
    centos        7
    java        1.8.0_45
    maven        3.5.2
    git         1.8.3.1
    jenkins     2.190.1

## 一、新建任务 ##

1、创建一个pipeline

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70][]

## 二、Pipeline脚本 ##

1、点击流水线，输入脚本。

可以参考官网流水线示例[https://jenkins.io/zh/doc/book/pipeline/][https_jenkins.io_zh_doc_book_pipeline]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 1][]

pipeline {
        agent any 
        stages {
            stage('checkout') {
                steps {
                checkout([$class: 'GitSCM', branches: [[name: '*/master']],...
                }
            }
        }
    }

pipeline：是声明式流水线的一种特定语法，他定义了包含执行整个流水线的所有内容和指令的 "block"

agent：是声明式流水线的一种特定语法，它指示 Jenkins 为整个流水线分配一个执行器 (在节点上)和工作区。

stage：是一个描述 stage of this Pipeline的语法块。在 Pipeline syntax 页面阅读更多有关声明式流水线语法的\`stage\`块的信息。如 above所述, 在脚本化流水线语法中，stage 块是可选的。

steps：是声明式流水线的一种特定语法，它描述了在这个 stage 中要运行的步骤。

## 三、checkout获取GitHub上的项目代码 ##

1、使用流水线语法生成

2、登录GitHub，选择ssh链接，点击复制

3、选择checkout，输入GitHub复制的ssh链接，添加GitHub登录用户名密码

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 4][]

4、此页面底部点击生成流水线脚本，选中复制

5、选择替换，然后就点击应用并保存

## 四、构建过程 ##

1、点击构建，第一次构建需要到GitHub下载，会很慢

2、打开控制台，查看构建成功信息
