javax.persistence.PersistenceException: No Persistence provider for EntityManager named financas

Olá Pessoal!

Estou tentando testar meu projeto JPA utilizando o maven como meu gerenciador de dependencias, entretanto, ja nao sei mais qual previdencia tomar pois o programa estoura a exception :

Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named financas
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:61)
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:39)
    at br.com.financas.teste.TesteJPA.main(TesteJPA.java:19)

Eu instalei o Mysql Server na máquina, criei a base "financas" e inseri o persistence.xml dentro do diretório "src/main/resources/META-INF". Meu Pom.xml também se encontra configurado com as libs que eu acredito serem as necessárias para rodar o framework.

Segue o persistence.xml:

<persistence version="2.1"
    xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
             http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

    <!-- unidade de persistencia com o nome financas -->
    <persistence-unit name="financas">

        <!-- Implementação do JPA, no nosso caso Hibernate -->
        <provider>org.hibernate.ejb.HibernatePersistence</provider>

        <!-- Aqui são listadas todas as entidades -->
        <class>br.com.financas.modelo.Conta</class>

        <properties>
            <!-- Propriedades JDBC -->
            <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />

            <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost/financas" />

            <property name="javax.persistence.jdbc.user" value="root" />
            <property name="javax.persistence.jdbc.password" value="123" />

            <!-- Configurações específicas do Hibernate -->
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" />

            <property name="hibernate.hbm2ddl.auto" value="update" />
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.format_sql" value="true" />
        </properties>
    </persistence-unit>
</persistence>

E tambem o meu pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <!-- DEPENDENCIAS DE ORM [FIM] -->

</project>

Alguma ideia do que possa estar faltando ?

Deixe o persisntence neste caminho: seu_diretorio\workspace\financas\bin\META-INF

e verifique se o acesso e senha no persistence está correto.
