maven:mvn site 报错Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.3:site (default

报错:

Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.3:site (default-site) on project Hello: Execution default-site of goal org.apache.maven.plugins:maven-site-plugin:3.3:site failed: A required class was missing while executing org.apache.maven.plugins:maven-site-plugin:3.3:site: org/apache/maven/doxia/siterenderer/DocumentContent

解决：在pox.xml中加入插件（代码如下）

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

   
 <plugin>
      
<groupId>org.apache.maven.plugins</groupId>
   
   <artifactId>maven-site-plugin</artifactId>
      
<version>3.3</version>
     
 <configuration>
       
 <locales>zh_CN</locales>
   
   </configuration>
    
</plugin>
 
 </plugins>
</build>

结果：

项目中多了site文件夹
