java - 将 JDA discord bot 上传到 heroku

问题描述

解决方案

MusikController.java:[18,39] cannot find symbol，MusikController.java的第18行有一个符号找不到。

可能的修复：[WARNING] File encoding has not been set, using platform encoding UTF-8, i.e. build is platform dependent!正如消息所说，构建依赖于平台。这可能在您的 PC 上有效，但无法使用默认平台编码 UTF-8 来读取我之前在服务器上提到的特定符号。
