Maven 不仅仅是一款项目构建和依赖管理工具，它还能够聚合项目信息，促进项目团队间地交流。POM 中可以包含各种项目信息，例如：项目描述、SCM 地址、许可证信息，开发者信息等。用户可以使用 Maven 提供的 maven-site-plugin 插件让 Maven 生成一个 Web 站点， 以站点的形式发布以上信息。

以 secondMaven 项目为例，修改其 pom.xml 中的配置，添加该插件到项目中。

<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/maven-v4_0_0.xsd">

            <version>1.0-SNAPSHOT</version>
            <systemPath>D:\maven\helloMaven\target\helloMaven-1.0-SNAPSHOT.jar</systemPath>
        </dependency>
    </dependencies>
</project>

打开命令行窗口，跳转到 secondMaven 的目录中，执行如下 mvn 命令。

mvn site

执行结果如下。

Maven 命令运行完毕后，可以在项目的 target\site 目录下找到 Maven 生成的站点文件，如下图。

双击打开 index.html 查看站点。
