消除maven构建时的各种告警

告警1号： 

[WARNING] Using platform encoding (GBK actually) to copy filtered resources, i.e. build is platform dependent! 

解决方法： 

Xml代码  

1. <build>  
2.         <plugins>  
3.   
4.             <plugin>  
5.                 <groupId>org.apache.maven.plugins</groupId>  
6.                 <artifactId>maven-resources-plugin</artifactId>  
7.                 <configuration>  
8.                     <encoding>UTF-8</encoding>  
9.                 </configuration>  
10.             </plugin>  
11.   
12.             <plugin>  
13.                 <groupId>org.apache.maven.plugins</groupId>  
14.                 <artifactId>maven-compiler-plugin</artifactId>  
15.                 <configuration>  
16.                     <encoding>UTF-8</encoding>  
17.                 </configuration>  
18.             </plugin>  
19.   
20.         </plugins>  
21.     </build>  

告警2号： 

[WARNING] Warning: selected war files include a WEB-INF/web.xml which will be ignored 
(webxml attribute is missing from war task, or ignoreWebxml attribute is specified as 'true') 

解决方法： 

Xml代码  

1. <plugin>  
2.                 <groupId>org.apache.maven.plugins</groupId>  
3.                 <artifactId>maven-war-plugin</artifactId>  
4.                 <version>2.1.1</version>  
5.                 <configuration>  
6.                     <packagingExcludes>WEB-INF/web.xml</packagingExcludes>    
7.                 </configuration>  
8.             </plugin>  

关于告警2，附带一提，很多时候会有将多个war合并成一个war的场景，这是用的是overlays选项，但是只有一个maven项目的web.xml会最终生效 

所以其他的maven项目中可以不放web.xml，但是对于packaging类型是war的maven工程，默认是必须要有web.xml的，这时候可以使用以下配置： 

Xml代码  

1. <plugin>  
2.                 <groupId>org.apache.maven.plugins</groupId>  
3.                 <artifactId>maven-war-plugin</artifactId>  
4.                 <configuration>  
5.                     <failOnMissingWebXml>false</failOnMissingWebXml>  
6.                 </configuration>  
7.             </plugin>
