Android Studio 拒绝运行 main() [英] Android Studio refuses to run main()

问题描述

重现步骤:

1. 在 Android Studio 中启动一个新项目(带有最新更新)；
2. 创建一个新类并像往常一样添加 main()；
3. 右键单击类以运行 main() 作为测试.

package test;

public class Test {
    public static void main(String[] args) {
    }
}

通常我希望我可以 System.out.printLn("Hello World") 但这一次，无论是新项目，我都会收到以下错误:

Usually I expect I can just System.out.printLn("Hello World") but this time, no matter if it's a new project, I get the following error:

2:34:23 PM: Executing task 'Test.main()'...

在 Unity 中使用了多年 C# 之后，我 相当 对 Java 不熟悉，并且不知道所有这些东西试图告诉我什么.我用谷歌搜索过，但我发现最接近的是一种隐藏此错误的方法(假设代码仍在编译).我至少需要这段代码才能编译.

I am fairly new to Java after years of C# in Unity and have no idea what all this stuff is trying to tell me. I have googled but the closest I found was a way to HIDE this error (assuming code was still compiling). I need this code to at least compile.
