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"> <modelVersion>4.0.0</modelVersion> <groupId>net.biancheng.www</groupId> <artifactId>secondMaven</artifactId> <packaging>jar</packaging> <version>1.0-SNAPSHOT</version> <name>secondMaven</name> <url>http://maven.apache.org</url> <build> <plugins> <!--添加site 插件--> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-site-plugin</artifactId> <version>3.7.1</version> </plugin> </plugins> </build> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>net.biancheng.www</groupId> <artifactId>helloMaven</artifactId> <scope>system</scope> <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。
