## 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、jenkins全局工具配置 ##

1、系统管理--全局工具配置![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70][]

2、JDK

别名：自定义

JAVA\_HOME：java的路径（解压缩包方式安装）

可以勾选自动安装，这里是取消的

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 1][]

3、Git（yum安装）

4、Maven

Name：自定义

MAVEN\_HOME：maven的路径（解压缩包方式安装）

可以勾选自动安装，这里是取消的

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 2][]

## 二、参数化构建过程 ##

1、添加参数

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 3][]

2、设置项目名称，选项可以设置多个。pipeline脚本可以调用名称变量

## 三、Pipeline脚本 ##

1、编辑脚本

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 4][]

pipeline {
        agent any
        tools { 
            maven "maven-3.5.2"
        }
        stages {
            stage('check out') {
                steps {
                    checkout([$class: 'GitSCM', branches: [[name: '*/master']], ...
                }
            }
            stage('building dependency') {
                steps {
                    sh '''
    					mvn -f company-common-pom  clean install -Dautoconfig.skip=true -Dmaven.test.skip=false -Dmaven.test.failure.ignore=true
    					mvn -f company-common-lib  clean install -Dautoconfig.skip=true -Dmaven.test.skip=false -Dmaven.test.failure.ignore=true
    				'''	
                }
            }
            stage('building selected project') {
                steps {
                    sh '''
    					mvn -f ${single_project_name}  clean install
    				'''	
                }
            }
        }
    }

tools：使用maven工具构建

building dependency：可选，如果没有依赖关系可跳过

building selected project：构建选定的项目

mvn -f：指定构建项目目录，该目录下一定要存在pom.xml文件（因为这里是根据pom.xml文件去构建的）

clean install：先清除之前构建生成的文件，并重新构建；后面接的选项可有可无

注意：因为mvn默认是国外源，有可能构建失败。这时修改mvn地址为阿里可以加快速度

[root@jenkins3 ~]# vim   /opt/apache-maven-3.5.2-aliyun/conf/settings.xml

2、点击构建

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 6][]

3、构建成功

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 7][]

4、到项目对应的工作目录查看，生成了以.jar为后缀的文件。

![2019110515425640.png][]

这里生成的文件名是由项目目录下的pom.xml的<artifactId>定义

定义文件类型<packaging>

![20191105171635276.png][]

## 四、启动.jar包 ##

1、手动输入java -jar可以直接启动\*.jar文件

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 8][]

2、查看java端口是8761,（8080是jenkins正在使用的端口）

![20191105154852396.png][]

3、网页访问

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 9][]

接下来会结合dockerfile构建为docker镜像
