模塊聲明一個servlet類.......，但web.xml中有沒有相應的映射

Question

我已經COMMITED Maven項目使用svn其工作在我的機器上，但是當其他的Maven在項目導入他們得到異常：

模塊聲明一個servlet類.......，但web.xml沒有 對應的映射;請添加以下行到您的web.xml

並且這個類屬於我的項目使用的庫。我不明白是什麼問題。請幫幫我。

module.gwt.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<module rename-to='engile'> 
    <!-- Inherit the core Web Toolkit stuff.      --> 
    <inherits name='com.google.gwt.user.User'/> 

    <!-- Inherit the default GWT style sheet. You can change  --> 
    <!-- the theme of your GWT application by uncommenting   --> 
    <!-- any one of the following lines.       -->

你需要檢查所有的接口延伸RemoteService，並已申報了RemoteServiceRelativePath註釋，確保所有這樣的相對路徑被映射在web.xml

示例 - https://developers.google.com/web-toolkit/doc/latest/tutorial/RPC

@RemoteServiceRelativePath("stockPrices") 
public interface StockPriceService extends RemoteService { 
} 

被映射爲

<!-- Servlets --> 
    <servlet> 
    <servlet-name>stockPriceServiceImpl</servlet-name> 
    <servlet-class>com.google.gwt.sample.stockwatcher.server.StockPriceServiceImpl</servlet-class> 
    </servlet> 

    <servlet-mapping> 
    <servlet-name>stockPriceServiceImpl</servlet-name> 
    <url-pattern>/stockwatcher/stockPrices</url-pattern> 
    </servlet-mapping>
