Estou usando o Java 11, e o Intellij, mas o mesmo erro acontece no eclipse.
Eu consegui arrumar mas para isso eu coloquei o maven no projeto (minha opção), e adicionei a dependência mais atualizada, aparentemente essa versão do curso esta com alguma incompatibilidade com as minhas versões, mas como eu sou novo na area não sei se isso faz sentido ou se foi isso mesmo o que aconteceu.
