Erro ao rodar o projeto após ter criado a classe AgendamentoEmailDao | EJB com Java EE 8: API Rest com WildFly 15

Eu executei os comandos pelo jboss-cli e mesmo assim não está indo. Baixei o connector duas vezes, uma pelo site(mysql-connector-java-8.0.18) no formato .tar e outra usando Maven(mysql-connector-java-8.0.15).

Não é possível adicionar um datasource no standalone manualmente?

Resolvi criando na mão o datasource e criando o arquivo persistence.xml, talvez só precisasse criar o persistence, mas achei estranho porque os comandos executados no jboss-cli não criaram um datasource no standalone.full-xml.

standalone.full-xml
