java - IntelliJ 无法编译为 "Java resource does not exist"

Question

我在 src 文件夹中使用 IntelliJ 社区版 2016.1 和单个文件“test.java”。

每当我编译或制作项目时，我都会收到以下错误。出了什么问题？遗憾的是，Google 上没有关于可能出现问题的信息。

您必须使用您的模块定义在 src 目录中创建 module-info.java 文件。

参见:http://openjdk.java.net/projects/jigsaw/spec/sotms/#module-declarations

例子:

module com.foo.bar { }
