Nao consigo gerar automaticamente a tabela produto

Criei normalmente via terminal o BD casa do codigo, porem mesmo atualizando o tomcat e dando um show tables no banco, a tabela produtos nao é criada,

estou usando a versão Mysql 8.0.16 MacOs HighSierra

tentei também alterando conforme abaixo: props.setProperty("hibernate.hbm2ddl.auto", "create-drop");

antes estava update, mudei para create-drop

Por fim, recebo erro 500

Bom dia Fabiano, se está com erro 500 pode ser que o hibernate nem tenha rodado, me fale mais sobre o erro no console para vermos o que está acontecendo

Boa noite, Guilherme segue erro no console
