我正在使用eclipse luna的最新GAE java sdk和eclipse插件。 我的项目包含使用maven（like here）的Java模块。
当我尝试从eclipse部署ear项目时，我遇到了这个异常：
Caused by: com.google.apphosting.utils.config.AppEngineConfigException: Application directory '--PATH-TO-MY-DEV-SERVER--/module-1.0.war' must exist and be a directory.

引用的模块在部署时不会解压缩。它们只作为.war文件存在！
我在eclipse中使用maven import导入了项目。我还创建了新的工作区，并多次删除和清理服务器目录。到目前为止没有成功。
