Deploying war with dependency resulting in ClassNotFoundException

I want to use the Enities provided by my data-handler in my controller-test project. The data-handler is set as an dependency in controller-test and I get no compile errors, however, when I want to deploy it I get this exception:

Caused by:java.lang.ClassNotFoundException: org.test.SomeEntityRepo from [Module deployment.controller-test.war:main" from Service Module Loader]

When I put SomeEntity and SomeEntityRepo into the Controller-test project everything works as it should.

It's a really simple setup and I just started to work with EE and DI so I am really frustrated.

I copied the key parts of the structure from one of the wildfly quickstart samples.

Please help :(

Project data-handler:

Class: SomeEntity

@Entity
public class SomeEntity implements Serializable
{
  @Id
  protected long id;
  // Getter and Setter
}

Class: SomeEntityRepo

@Stateless
public class SomeEntityRepo {

    @Inject
    private EntityManager em;

    public SomeEntity findOne(long id) {
        return em.find(SomeEntity.class, id);
    }
}

Class Resource

public class Resources {

    @PersistenceContext
    @Produces
    private EntityManager entityManager;
}
