Oi Alex, você pode postar o código de suas classes aqui? Meu chute é que você tenha feito algum import de classe errado.
esse é o persistence.xml

}Oi, Alex suas classes estão corretas. Fiz uma pesquisa aqui e essa exceção ocorre quando usa o java 9 e não vem mais no classpath dessa versão. Você provavelmente está utilizando o java 9 e precisa colocar os jars do jaxb para funcionar
Olá, Thais! fazendo uma pesquisa também, vi quem deveria ir no "Run Configurations" e colocar "--add-modules java.xml.bind" no VM Arguments. Depois disso surge uma nova Exeception:

Seu persistence.xml está na pasta src/META-INF?
Sim. Tô vendo pessoas com o mesmo problema também, estando com o persistence.xml no lugar certo. Mas não encontrei nenhuma solução até agora.
Seguindo algumas recomendações, instalei o "hibernate-annotations.jar" e o "hibernate-entitymanager.jar" que estavam faltando. Agora o seguinte erro acontece:

at br.com.caelum.financas.teste.Teste.main(Teste.java:17)Oi, veja se todas as dependências do hibernate estão na mesma versão senão pode gerar incompatibilidade de versões.
Você excluiu o hibernate-annotations.jar e o hibernate-entitymanager.jar ? (obs.: não tenho certeza se isso resolveria)
Oi Alex, conseguiu resolver? Este post do blog da Caelum pode te ajudar: http://blog.caelum.com.br/erros-com-jaxb-no-java-9/
removi o java 9 do meu pc e instalei o java 8. ao tentar fazer tudo de novo, do mesmo jeito, ocorre a seguinte exception:

... 29 moreCerto, Alex. Como você modificou suas configurações para o projeto usar o java 9 é esperado que agora, ao mudar para o java 8, o problema continue. Sugiro você seguir as configurações do Hibernate de acordo com as aulas do curso (tanto classes de configuração como o pom.xml) e entrar na pasta local do maven em sua máquina (.m2) e apagar o pasta repository de lá para que o maven faça o download das dependências novamente.
Ou você poderia enviar seu projeto (pelo github ou upar em algum lugar e mandar o link) pra gente diagnosticar mais rápido o problema
