規範的maven專案應該為

myproject/    
|-- pom.xml    
`-- src    
    |-- main    
    |   |-- java    
    |   |   `-- com    
    |   |       `-- mycompany    
    |   |-- resources    
    |   `-- webapp    
    |       |-- WEB-INF    
    |       |   `-- web.xml    
    |       `-- index.jsp    
    `-
 
- test    
        |-- java    
        |   `-- com    
        |       `-- mycompany    
        `-- resources

如果專案是非規範的maven專案，打包時需修改pom.xml檔案，否則打包後會丟失檔案。

程式碼為：

  <build>
      <sourceDirectory>src/</sourceDirectory>  
       <resources>  
           <resource>  
               <directory
 
>src</directory>  
               <excludes>  
                   <exclude>**/*.java</exclude> 
               </excludes> 
           </resource> 
           <resource> 
               <directory>src/main/java/resources</directory> 
               <excludes
 
> 
                   <exclude>**/*.java</exclude>  
               </excludes>  
           </resource>  
       </resources>       
    <plugins> 
            <plugin>    
                <groupId>org.apache.maven.plugins</groupId>    
                <artifactId>maven-war-plugin</artifactId>    
                <version>2.1.1</version>    
                <configuration>    

                      <webXml>${basedir}/webapp/WEB-INF/web.xml</webXml>            
                      <warSourceDirectory>webapp</warSourceDirectory> 
                </configuration>    
            </plugin>
    </plugins>
</build>
