java.lang.NoClassDefFoundError：com/google/gwt/core/ext /生成器

我想在我的項目中添加GXT。爲此，我跟着 setting up your first ext gwt project in eclipsejava.lang.NoClassDefFoundError：com/google/gwt/core/ext /生成器

我的Java打造專業化路徑給出的所有步驟是這樣的

Java build Path

我的XML文件是

<?xml version="1.0" encoding="UTF-8"?> 

<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.5.1//EN" 
"http://google-web-toolkit.googlecode.com/svn/tags/2.5.1/distro-source/core/src/gwt- module.dtd"> 
<module rename-to='hellogxt'> 
<!-- Inherit the core Web Toolkit stuff.      --> 
<inherits name='com.google.gwt.user.User'/> 


<inherits name='com.google.gwt.user.theme.clean.Clean'/> 

<inherits name="com.extjs.gxt.ui.GXT" /> 
<!-- Specify the app entry point class.       --> 
<entry-point class='com.hello.gxt.client.HelloGXT'/> 

<!-- Specify the paths for translatable code     --> 
<source path='client'/> 
<source path='shared'/> 

</module>

我得到這個錯誤

你應該在你的類路徑GXT-2.2.5-gwt2.jar和GXT-2.2.5-gwt22.jar和GXT-2.2.5-gwt17.jar。

不，這是錯誤的（我不確定它是否可以解決問題）。根據你使用的是哪個版本的GWT，你的類路徑中應該有* 1 *這三個jar。由於問題顯示了最新的GWT（2.5.1），只能使用* gxt-2.2.5-gwt22.jar文件。 – 2013-03-25 17:24:39

我添加了所有的罐子。但仍然有同樣的錯誤.. seee修改後的圖像 – GameBuilder 2013-03-25 17:31:25

@HoucernBerrayans：添加了所有3個罐子：但錯誤是一樣的。 – GameBuilder 2013-03-25 17:35:16
