在Heroku上部署discord BOT java jda

Question

你好，我想在heroku上推我的discord机器人，但我使用JDA的Library，当我在heroku上时，我将我的github项目链接到他，我有以下错误：

 !     No default language could be detected for this app.
        HINT: This occurs when Heroku cannot detect the buildpack to use for this application automatically.
        See https://devcenter.heroku.com/articles/buildpacks

但是我有一些java文件，我想知道我的代码和库是否可以放在heroku上

我的主要意见是：

    package fr.Bot;

import net.dv8tion.jda.client.entities.Group;

import net.dv8tion.jda.core.*;
import net.dv8tion.jda.core.entities.*;

    JDA jda ;



    /**

    public static void main(String[] args)

    }

    private void run(String[] args) {

        initServeur();
        try

            @Override
            public void actionPerformed(ActionEvent ae) {
                cleanMsg();
            }

            private void cleanMsg() {
                c.delete().reason("clean").queue();
                t.stop();
            }
        });
        Timer timer;
        timer = new Timer(30000, new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent ae) {
                onChangeServer();
            }
        });
        timer.start();
        while (!stop) {
            Scanner scanner = new Scanner(System.in);
            String cmd = scanner.next();
            if (cmd.equalsIgnoreCase("stop")) {
                exit();
            }
        }
    }

    @Override
    public void onMessageReceived(MessageReceivedEvent event)
    {

        // event management

是的，你可以，但是为了让heroku自动检测你的Java应用，你需要使用maven并包含pom。xml。检查这个https://devcenter.heroku.com/articles/java-support
