一、Maven是什么

Maven是一个采用纯Java编写的开 源项目管理工具。Maven采用了一种被称之为project object model (POM)概念来管理项目,所有的项目配置信息都被定义在一个叫做POM.xml的文件中,通过该文件,Maven可以管理项目的整个声明周期,包括编 译,构建,测试,发布,报告等等。目前Apache下绝大多数项目都已经采用Maven进行管理。而Maven本身还支持多种插件,可以方便更灵活的控制 项目。

四、创建第一个maven项目

此处假设你所使用的Eclipse已经有了maven插件,如果没有,可自行搜索安装。

new project--->maven project --> 勾选(cerate a simple project)-->next

    -->groupId 格式一般为 com.myconpany Artifact ID一般为项目名 packageing 为项目打包方式,jar将生产普通项目,war将生产web项目。

-->finish

如果packageing选择jar生产的项目结构如下:

假如项目需要使用log4j,那么我们只需要打开pom文件,加入类似如下配置

<dependency>
<groupId>org.apache</groupId>
<artifactId>log4j</artifactId>
<version>1.2.16</version>
</dependency>

假如需要使用junit 在pom配置文件重加入如下配置

        <dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>

1.当我们写好如上这样的配置之后,maven会自动在*仓库下载相关的jar包,jar包将会默认保持在当前电脑用户文件夹中 .m2文件中。

2.maven会自动下载A   jar所依赖的 Bjar包。例如 我们使用springmvc 只需在项目中加入 spring-web spring-webmvc 依赖就可以了,至于他们依赖的 beans,core什么的maven会自动依赖下载
