Oi pessoal, eu estou com um problema no projeto que eu acabei de começar. É a primeira vez que estou usando maven, e estou recebendo um erro muito estranho (pesquisei em todos os cantos como resolver, mas todas as soluções deram errado). Estou fazendo conexão com o Derby. Já testei com o Connection do JDBC, e a conexão deu certo, então o problema está no jpa mesmo.
Então, o erro que eu estou recebendo é o seguinte:

Exception running application trickstival.MainApp
O foco fica especialmente nessa linha:
Caused by: javax.persistence.PersistenceException: No Persistence provider for EntityManager named petPU
O erro ocorre nesta linha no meu código (que inclusive, é a primeira linha do código, já que eu queria testar a conexão):
Persistence.createEntityManagerFactory(“petPU”);
O meu persistence.xml está localizado em src/main/resources/META-INF (já que estou usando o Maven). Já tentei colocar o META-INF no src mesmo, mas deu outro erro, que dizia não encontrar o petPU.
Esse é o meu persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.format_sql" value="true"/>
</properties>
</persistence-unit>
</persistence>
Como eu disse, a conexão e o driver estão funcionando normalmente. Pensei na hipótese de estar faltando algum .jar, então dei uma olhada nos .jars que vem junto com o hibernate quando baixo direto do site, mas pelo jeito todos já estão no meu projeto:
