添加Maven依賴於GWT項目

我開始我的GWT項目，然後有人告訴我，這是很好的使用Maven，所以我決定試試，我加入Maven依賴於我的項目它產生了非常簡單的POM文件：添加Maven依賴於GWT項目

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchemainstance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven 4.0.0.xsd"> 
    <modelVersion>4.0.0</modelVersion> 
    <groupId>demo5</groupId> 
    <artifactId>demo5</artifactId> 
    <version>0.0.1-SNAPSHOT</version> 
    <packaging>war</packaging> 
</project>

我試圖運行目標GWT：編譯GWT：跑，當我運行它第一次下載很多罐子和卡住的，當我運行它第二次它gaves我：

如果這將會有所幫助，我正在eclipse Can下工作有人告訴我我做錯了什麼，我該如何解決這個問題？在此先感謝。

你是什麼意思添加maven依賴項目到你的項目？ – Lucas

抱歉不清楚，我的意思是在項目 – user902383

中啓用依賴關係，上面列出的'pom.xml'的內容不顯示_any_依賴關係。你在那裏添加了必要的依賴關係嗎？ – Lucas

創建項目並添加一些依賴項是不夠的。首先，您需要添加正確的依賴關係，codehaus插件以及適當的配置，當然還有適當的項目結構，以及web.xml和gwt描述符模塊。

使用maven啓動gwt最簡單的方法是從原型生成一個完整的項目。看看http://mojo.codehaus.org/gwt-maven-plugin/user-guide/archetype.html。

要生成的GWT項目，只需輸入您的控制檯：

mvn archetype:generate \ 
    -DarchetypeRepository=repo1.maven.org \ 
    -DarchetypeGroupId=demo5 \ 
    -DarchetypeArtifactId=demo5 \ 
    -DarchetypeVersion=2.4.0

接下來，您必須導入生成的項目到您的IDE，我建議你編譯它之前，你將推出託管模式使用下面的命令：

mvn gwt:run

您可以使用-maven標籤與包裝含有GWT SDK的webAppCreator工具，就像這樣：

webAppCreator -maven -out MyGwtProject com.mycompany.myproject.MyGwtProject
