无法在Intellij中运行Main类 [英] Cannot run Main class in Intellij

问题描述

我有以下项目结构

-ProjectRoot
---src
------Main
------examples
---libs

我的 src 文件夹在Intellij中被标记为 sources .

My src folder is marked as sources in Intellij.

现在，当我想运行Main class时，出现以下错误:

Now, when I want to run Main class, I get the following error:

Exception in thread "main" java.lang.ClassNotFoundException: Main

关于我在做什么错的任何想法?

Any ideas on what am I doing wrong?

这是我的主班:

public class Main {
    public static void main(String[] args) {
        System.out.println("hello world");
      }
    }

它没有任何包装声明.

推荐答案

清理项目，编辑运行配置，再次手动选择主类.如果您具有 src/main/java 结构，则可能不需要.

Clean the project, edit run configuration, choose the main class manually again. This probably wouldn't be needed if you had src/main/java structure.
