Erro ao tentar subir API java

Configs:

java version "1.8.0_221"
Java(TM) SE Runtime Environment (build 1.8.0_221-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)
mysql  Ver 14.14 Distrib 5.7.27, for Win64 (x86_64)
Windows 10

Tentei rodar o jar comentado nos vídeos, pois a API heroku está muito suja, mas ocorreu o seguinte problema:
