Jenkins02：Jenkins+maven+svn集成

1、安装Maven并配置环境变量

下载maven（windows下载zip包，linux下载tar.gz包），然后配置环境变量

在项目中使用maven，可以从java中央仓库中获取到项目所依赖的jar包，才能完成项目的部署。

1.1 Linux配置环境变量内容

export MAVEN_HOME=/usr/local/apache-maven-3.5.3  -- 选择自己正确的版本号export PATH=${PATH}:${MAVEN_HOME}/bin

配置完成后，输入source profile使环境变量生效

在终端输入mvn -v查看maven是否安装成功

1.2 Windows配置环境变量内容

添加环境变量
MAVEN_HOME=C:\Program Files\Maven\apache-maven-3.5.3在path后追加环境变量：%MAVEN_HOME%\bin

输出mvn -v检查是否安装成功

2、配置Jenkins中的jdk和maven环境变量

2.1 在Jenkins中点击系统管理->全局工具配置分别配置jdk和maven

2.1.1 配置jdk

2.1.2 配置maven

1. 安装插件Maven Integration plugin

2. 在全局配置工具中配置maven

3 安装搭建svn

安装文档地址：

4 构建Jenkins集成项目

1. 构建一个maven项目（需要先安装Maven Integration plugin插件）
   

1. 配置源码管理（svn）
   

1. 在Pre Steps下找到Build进行配置
   

5. 项目执行日志输出及解释

5.1 日志关键点展示

5.1.1 项目构建完成控制台输出

5.1.2 生成的jar包的路径

5.1.3 如果控制台报错找不到对应的jar包的解决办法

说明在maven的中央仓库无法下载到这个jar包，那么就需要找开发要对应的jar包然后放到控制台报错指示路径即可

5.2 日志输出完整展示

6. 打war包配置及出错指导

6.1 修改pom.xml文件

使用maven默认打包时打的jar包，如果要打war包需要修改pom.xml文件，修改方式如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.maven</groupId>
  <artifactId>JunitTest02</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  
  <!--  以下是添加的代码-->
  <dependencies>
      <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.11</version>
      </dependency>
  </dependencies>
  <!--  添加代码结束-->
  
  <!-- 将这里修改为war打包的时候就可以打war包 -->
  <packaging>war</packaging></project>

6.2 jenkins打包报错解决指导

6.2.1 错误展示

修改后，jenkins打包时，发现报错如下：

6.2.2 出错原因

maven的web项目默认的webroot是在src\main\webapp\WEB-INF。如果在此目录下找不到web.xml就抛出以上的异常。

6.2.3 问题解决

在src\main\webapp\WEB-INF下建立web.xml文件
