GWT编译在IDEA中失败：无法解析UserAgentAsserter

将我的开发环境迁移到一台新的笔记本电脑，并面临以下错误（这从来都不是一个轻松的过程）。 因此，我拥有的是：Windows 8、Intellij Idea 12、GWT 2.5.1，配置了一个简单的工件，它只生成“

GWT编译输出”

”：

但是没有改变，我仍然看到相同的“6个错误”信息

如果您能告诉我为什么会出现这个错误，我将不胜感激。谢谢

UPD. 将我的RichClient.gwt.xml文件的代码缩减为

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.5.0//EN" "http://google-web-toolkit.googlecode.com/svn/tags/2.5.0/distro-source/core/src/gwt-module.dtd">
<module rename-to='richclient'>
    <!-- Inherit the core Web Toolkit stuff. -->
    <inherits name='com.google.gwt.user.User' />
</module>

---

（未设置入口点），但仍然得到相同的错误

后来发现了这个。过时的jar，它不包括在原始项目的lib路径中，但设法潜入新配置的项目中

验证单元：
“jar:file:/D:/Projects/myProject/src/main/webapp/WEB-INF/lib/css3pie-0.1.jar”中的[ERROR]错误/com/google/gwt/user/client/UserAgentInfo.java'
[错误]第19行：无法解析导入com.google.gwt.user.client.UserAgentAsserter

拆下罐子就成功了
