我使用gwt和谷歌应用引擎开发了一个应用程序。直到现在我用我一直在使用gwt 2.7 lib和google app engine 1.51 lib。我想尝试将from gwt 2.7升级到2.8.1 lib，我有2，但我现在面临两个问题
我希望你能帮助我。
1）当我尝试运行项目时，我在devModeBase.class
中得到异常当我尝试运行项目时，我在devModeBase.class中得到异常 运行方法中的文件 这是run + exception的日志：

谢谢你们每个人
答案 0 :(得分：2)
我可以评论你的观点2.
GWT 2.8中不存在抱怨它丢失（com/google/gwt/core/ext/typeinfo/HasMetaData）的类。
所以你可能在某个地方引用旧罐子，例如gwt-dev / gwt-user 2.7等。这可能会导致许多其他问题（不排除在1中描述的那个）。所以我在找到其他地方之前先解决这个问题。
编辑：刚刚注意到你引用的是2.8.1而不是2.8.0;不知道2.8.1出局了。我刚刚重新检查了2.8.1，我的答案仍然适用。
