1.什么是maven仓库？
1.1 仓库和构件
仓库指的是在某个位置统一存储所有maven项目共享构件。
构件可以是一个插件 可以是一个jar包也可以是我们自己输出的构建(或者说对项目打的包)
1.2 仓库分类
1.3 仓库中寻找构件的过程？
2.什么是maven坐标(依赖)?

2.1 坐标(依赖)定义
坐标是标识构件在仓库中的唯一位置。
2.2 如何添加坐标(依赖)?
例如：添加一个spring-test.jar的依赖过程
1).打开maven的中央仓库：http://search.maven.org/
2).搜索仓库：
http://search.maven.org/#artifactdetails%7Corg.springframework%7Cspring-test%7C3.2.16.RELEASE%7Cjar
3).配置maven pom，添加一组依赖<dependencies>，拷贝上面坐标地址：
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>3.2.16.RELEASE</version>
</dependency>
</dependencies>
3.如何发布项目到仓库
mvn install ：发布到本地仓库
mvn deploy : 发布到远程仓库
对本地项目发布到本地仓库：(本地仓库地址：D:\mavenRepository3\com\sohu\train\maven-02\1.0-SNAPSHORT\maven-02-1.0-SNAPSHORT.jar)
