运行 GWT 开发者模式时出错

Question

从 Intellij 以 GWT 开发模式启动我的应用程序时。我收到以下错误：-

 ERROR: Failed to create an instance of 'com.vaadin.client.ApplicationConnection' via deferred binding

我从错误中了解到我错过了继承任何模块。但是这个 "com.vaadin.client.ApplicationConnection" 是在哪个模块中执行的，因为它是 vaadin 本身的 class。我正在使用 vaadin 7.4.6 版本 <inherits name="com.vaadin.DefaultWidgetSet" /> 已经继承。

我能够解决这个问题并在这里分享它，它可能对其他人有帮助。

从目标中删除了所有旧的已编译小部件集
重新编译整个项目

然后我发现，它开始正常工作了。
