[Java][Maven]Maven部署Web项目报错webxml attribute is required

mvn install一个web项目时，报错如下：Error assembling WAR:webxml attribute is required

1. [ERROR] Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.1.1:war   
   (default-war) on project com.alpha.webapp: Error assembling WAR:   
   webxml attribute is required (or pre-existing WEB-INF/web.xml if executing in update mode) -> [Help 1]  
   [ERROR]   
   [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.  
   [ERROR] Re-run Maven using the -X switch to enable full debug logging.  
   [ERROR]   
   [ERROR] For more information about the errors and possible solutions, please read the following articles:  
   [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException  

   
   原因：

   maven的web项目默认的webroot是在src\main\webapp。如果在此目录下找不到web.xml就抛出以上的异常。
   

   解决办法：需要在pom.xml中增加<webResources>配置，如下：

   <build>  
   <finalName>simple-webapp</finalName>  
   <plugins>  
       <plugin>  
           <groupId>org.apache.maven.plugins</groupId>  
           <artifactId>maven-war-plugin</artifactId>  
           <version>2.1.1</version>  
           <configuration>  
     
                 <webXml>WebContent\WEB-INF\web.xml</webXml>          
     
           </configuration>  
       </plugin>  
   </plugins>  
    </build>
