Java错误：找不到或加载主类测试

Question

搜索并且找不到导致此操作无效的原因。尝试运行一个简单程序时出现此错误：

public class Test {
    public static void main( String[] args) {
        System.out.println("Hello");
    }
}

我使用齿轮自动生成launch.json文件。我也从未真正做过任何事情。我正在使用带有Redhat Java和Java调试器扩展的VSCode。我已经安装了Java 1.8.0（+ jdk）

launch.json代码：

{
"version": "0.2.0",
"configurations": [
    {
        "type": "java",
        "name": "Debug (Launch)-Test",
        "request": "launch",
        "cwd": "${workspaceFolder}",
        "stopOnEntry": false,
        "mainClass": "Test",
        "args": ""
    },
    {
        "type": "java",
        "name": "Debug (Attach)",
        "request": "attach",
        "hostName": "localhost",
        "port": 0
    }
]
}

删除.vscode/launch.json对我有用。
