solução

Consegui resolver o problema com o Maven.

Configurei o pom.xml do Maven atualizando as dependências do Hibernate com a última versão!

<dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-entitymanager</artifactId>
            <version>5.4.3.Final</version>
        </dependency>

Perfeito Ricardo!

Bons estudos.
