播放框架2.0-意外的异常-找不到密钥:源 [英] play framework 2.0 - unexpected exception - Key Not Found : Source

问题描述

尝试启动我的Play 2.0应用时，我收到未找到密钥的错误消息.实际上，我认为我没有进行任何更改，并且此错误刚刚出现.其实我做了一件事.我打开了target/scala-2.9.1/src_managed/main文件夹中的文件，然后将其关闭(我没有做任何更改，也没有保存或删除文件).但是在重新加载应用程序后，出现了此错误.知道我能做什么吗?

I'm getting a key not found error message while trying to start my Play 2.0 app. I actually think that I did not change anything, and this error just popped-up. Actually I did one thing. I opened the files in the folder target/scala-2.9.1/src_managed/main and closed it (I did not changed anything, nor saved or deleted a file). But after reloading the app I got this error. Any idea what I can do?
