有什么问题?

我建立了一些关于它的讨论,但没有解决方案 https://plus.googleapis.com/communities/116543000751323604177/stream/1cf77106-8055-472e-abb2-ac58a512b663

2 个答案:

答案 0 :(得分:3)

可能是您在类路径中有一个不兼容的ASM版本。 GWT需要ASM 5 +

答案 1 :(得分:0)

类路径可能有一些配置错误。在我的情况下,我有一个2.8项目工作得很好,但由于某种原因,较新的项目有堆栈竞赛。我不知道是什么导致了这种情况,但我的解决方案是改变.classpath的这一部分:

    <classpathentry kind="con" path="com.google.appengine.eclipse.core.GAE_CONTAINER/App Engine"/>
    <classpathentry kind="con" path="com.google.gwt.eclipse.core.GWT_CONTAINER"/>

为:

   <classpathentry kind="con" path="com.google.appengine.eclipse.core.GAE_CONTAINER"/>
   <classpathentry kind="con" path="com.google.gwt.eclipse.core.GWT_CONTAINER/GWT"/>
