java - Play framework: Routing broken

Question

I am having some issues with the Play framework. It won't compile anymore, giving the following error:

java: cannot find symbol
  symbol:   variable debug
  location: class controllers.Application

Indeed this line in Apllication.java is underlined in red in IDEA, but as far as I remember that has always been the case:

I do have a debug.scala.html file under views. If I change the above return statement to return ok(); everything compiles fine, but that of course removes all functionality.

PS: The fact that that IDEA thinks that there are errors in the Play code, even when there are none and it all compiles fine, makes debugging somewhat difficult, I find. (As in screenshot above.) Is there a fix for this?

Answer 1

Idea 尝试通过用专用替换通配符导入来优化导入，因此您可以轻松地手动添加此导入：

import views.html.debug;

提示：另一方面，尽量不要将您的视图命名为debug等info。-PlayLogger有这样的方法，所以如果您不小心编写导入，您可能会不小心在错误的地方使用它，所以最好将这些视图称为debugView.scala.html？

Answer 2

发现错误：早些时候，我做了一些重构，IDEA决定从文件中删除以下导入，因为它认为它没有被使用：

import views.html.*;
