我一直在开发Java Jersey RESTful Web应用程序，并且一切正常，直到我再次编译并得到以下编译器错误。
我已经用Google搜索了这个问题，许多人建议做File->Invalidate Caches/Restart...，但这没有用。
我还尝试手动删除Mac OS X目录：/Libary/Caches/IntellijIdea14中的文件。这也没有用。
以前有没有人经历过？我很困惑为什么会出现此错误，以及到底是什么原因引起的。这肯定拖延了我的发展！

最佳答案
奇怪的是，以下代码有效（因为这是一个Maven项目）：
$ mvn clean
我想清洁模块一定要做些什么，因为此后构建就很好了。我必须相信这是某种Intellij错误。
