求GWT大神解决“插件无法连接到开发服务器”问题。。。。

前提:eclipse、浏览器均已正确安装GWT插件,按照教程成功创建并运行一个Web Application Project
问题:从公司SVN上下载一个GWT项目到本地新的workshop中,编译正常,但在浏览器中访问时出现“Plugin failed to connect to Development Mode server at 127.0.0.1:9997”,在GWT Development Mode窗口中出现错误信息:
Unable to find type 'com.atrct.core.gwt.client.portal'
[ERROR] Hint: Check that the type name 'com.atrct.core.gwt.client.portal' is really what you meant
[ERROR] Hint: Check that your classpath includes all required source roots
[ERROR] Failed to load module 'portal' from user agent 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.153 Safari/537.36' at 127.0.0.1:59069

下载的工程本身没有问题,同事的可以正常运行~~~~~
