@Toshiba1127 Are you trying to launch a released jar file, or are you using IntelliJ IDEA to build and run it?

ghost commented 4 years ago

I'm trying to launch it and also via CMD java -jar

lequietriot commented 4 years ago

@Toshiba1127 Try building it in IntelliJ IDEA instead, there were some issues with the jar file itself running properly in some cases.

I installed IntelliJ IDEA and it took me very long time to figure it out how to configure and build. It works, but gave up because it was too buggy. I got the mp3 from other sites I needed
