java - Android Studio 拒绝运行 main()

Question

重现步骤:

1. 在 Android Studio 中启动一个新项目(使用最新更新)；
2. 像往常一样创建一个新类并添加 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") 但这次，无论它是否是一个新项目，我都会收到以下错误:

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

在 Unity 中使用 C# 多年之后，我对 Java 还算陌生，不知道这些东西想告诉我什么。我已经用谷歌搜索过，但我发现的最接近的是隐藏此错误的方法(假设代码仍在编译)。我至少需要这段代码才能编译。

Quick Fix : You can run using Run with Coverage.. See Image Below.

Permanent Solution: Add <option name="delegatedBuild" value="false" /> and sync project.

内部文件gradle.xml在路径E:\Project\.idea\gradle.xml下。请参见下图。
