Visual Studio代码导入库

Question

我正在使用Visual Studio CodeJava，我想在使用库时调试我的代码。但是每当我开始调试时，我都会收到以下错误：

Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
    IO cannot be resolved
    IO cannot be resolved
    IO cannot be resolved

    at TestClass.main(TestClass.java:6)

例如，使用以下代码：

import AlgoTools.IO;

public class TestClass {
    public static void main(String[] args) {
        int a, b;
        a = IO.readInt("Please enter a number ");
        b = IO.readInt("Please enter another number ");

        IO.println("Your number is: " + (a + b));
    }
}

但是当我使用javac在cmd或PowerShell中编译代码时

我还应该提到，我在我的CLASSPATH中添加了. jar Libary的路径。

我正在使用默认的“启动”调试配置：

{
    "type": "java",
    "name": "Debug (Launch)",
    "request": "launch",
    "cwd": "${workspaceFolder}",
    "console": "internalConsole",
    "stopOnEntry": false,
    "mainClass": "",
    "args": ""
},

您应该安装一个名为“java扩展包”的扩展和java maven。或者安装离线扩展。单击此处获取扩展名
