Java 部署时应用引擎ClassNotFoundException

部署后运行我的应用程序时出现以下错误：

Could not instantiate listener com.utilitiessavings.usavappv7.server.guice.GuiceServletConfig
java.lang.ClassNotFoundException: com.utilitiessavings.usavappv7.server.guice.GuiceServletConfig

它后面还有几个其他错误，但由于某种原因，我的GuiceServlet（在我的web.xml中定义）似乎无法实例化。下一个错误是相同的，但是对于我的uploadServlet，有几个错误是由Servlet不可用引起的

我的应用程序在开发模式下运行良好，使用GWT 2.5.1、GAE 1.8.5和GWTP 1.0.1

这是这个项目的第一个maven版本，我不确定是否正确部署了它。我只是使用来自GoogleEclipse插件的常规部署方法

感谢任何指点。

发现我做错了什么。我需要使用maven gae插件来部署它（正如在我的pom.xml中设置的那样，一定是不知何故遗漏了这一点）

使用goal

gae:deploy

运行maven构建成功了
