我正试图通过github在heroku上部署一个用javamaven编程的telegrambot，在本地运行时工作。当我通过git在heroku上编译它时，它告诉我：

[INFO] ------------------------------------------------------------------------
       [INFO] BUILD SUCCESS
       [INFO] ------------------------------------------------------------------------
       [INFO] Total time:  7.117 s

       Released v5
       https://region-color-telegram-bot.herokuapp.com/ deployed to Heroku

但是机器人不工作。
当我点击heroku上的“打开应用程序”时，它会显示应用程序错误，并在日志compair中显示：

在我的文件里我写了这样一句话：

worker: java -jar target/RegionColor-0.0.1-SNAPSHOT.jar TelegramBot.RegionColor.Main

（我也试着用web改变worker）
这就是pom.xml的内容：

从pom中的库中可以看到，bot对mysql数据库进行了一些调用，但这已经是在线托管的并且可以工作。
不幸的是，我对pom或procfile的使用缺乏经验，如果我写了一些无稽之谈，我会提前道歉。有人能告诉我要改变什么才能让机器人工作吗？谢谢
