如何创建 Maven 项目文档。

比如我们在 C:/MVN 目录下，创建了 consumerBanking 项目，Maven 使用下面的命令来快速创建 java 项目：

mvn archetype:generate -DgroupId=com.companyname.bank -DartifactId=consumerBanking -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

修改 pom.xml，添加以下配置（如果没有的话）：

<project> ... <build> <pluginManagement> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-site-plugin</artifactId> <version>3.3</version> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-project-info-reports-plugin</artifactId> <version>2.7</version> </plugin> </plugins> </pluginManagement> </build> ... </project>

不然运行 mvn site 命令时出现 java.lang.NoClassDefFoundError: org/apache/maven/doxia/siterenderer/DocumentContent 的问题， 这是由于 maven-site-plugin 版本过低，升级到 3.3+ 即可。

打开 consumerBanking 文件夹并执行以下 mvn 命令。

C:\MVN\consumerBanking> mvn site

Maven 开始生成文档：

打开 C:\MVN\consumerBanking\target\site 文件夹。点击 index.html 就可以看到文档了。
