How can I include JPA 2.1 feature in Maven project?

Im using Maven 3, JPA 2.1 and Hibernate 4.3.5.Final. I want to use JPA 2.1 because it offers several features, especially adding conditions to the outer outer join clauses. I have included the following dependencies in my Maven project ...

    <dependency>
        <groupId>org.hibernate.javax.persistence</groupId>
        <artifactId>hibernate-jpa-2.1-api</artifactId>
        <version>1.0.0.Final</version>
    </dependency>   
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-validator</artifactId>
        <version>4.3.2.Final</version>
        <exclusions>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>slf4j-api</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>4.3.6.Final</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-ehcache</artifactId>
        <version>4.3.6.Final</version>
    </dependency>

      

        
        
        
      

    

However, when I try to compile the following, I get a compilation error ("cannot find the symbol") in the ".on (" section.

    final CriteriaBuilder cb = m_entityManager.getCriteriaBuilder();
    CriteriaQuery<Message> query = cb.createQuery(Message.class);
    Root<Message> messageRoot = query.from(Message.class);
    final Join<Message, Group> groupJoin = messageRoot.join(Message_.group);
    final Join<Message, MessageReadDate> msgReadDateJoin = messageRoot.join(Message_.messageReads, JoinType.LEFT);
    msgReadDateJoin.on(msgReadDateJoin.get(MessageReadDate_.recipient), recipient);

      

        
        
        
      

    

What libraries do I need to include in my Maven project in order to get JPA 2.1 and hence the "join.on" functionality?
