Olá! Não entendo nada de Java e nem tenho nada de ambiente java na minha máquina. O arquivo jar do curso mas não está rodando aqui. Tentei esses os dois comandos abaixo.
java -jar cdcreact-1.0.0-SNAPSHOT.jar
java -Dspring.datasource.username=root -Dspring.datasource.password= -jar cdcreact-1.0.0-SNAPSHOT.jar
Uso Windows e para executar comandos o Git Bash. Os erros que aparecem pra mim são esses:
(...)
