Play Framework kann nicht lesen db config und injizieren JPAApi

Question

Ich versuche und nicht zu spielen, spielen 2.5.

Mein Controller:

public class HomeController extends Controller { 

    private JPAApi db; 

    @Inject 
    public HomeController(JPAApi api) { 
     this.db = api; 
    } 

    public Result index(String name) { 
     return ok(views.html.index.render("hello", name, Collections.singletonList("world"))); 
    } 
} 

Meine conf \ META-INF \ persistence.xml

<persistence 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" 
      version="2.1"> 
    <persistence-unit name="readwritePU" transaction-type="RESOURCE_LOCAL"> 
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider> 
    <non-jta-data-source>ReadWriteDS</non-jta-data-source> 

    <properties> 
     <property name="hibernate.connection.isolation" value="1" /> 
     <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQL94Dialect" /> 
     <property name="hibernate.cache.use_second_level_cache" value="false" /> 
     <property name="hibernate.cache.use_query_cache" value="false" /> 
    </properties> 
    </persistence-unit> 
</persistence> 

Meine conf \ application.conf

jpa.default=readwritePU 

db { 
    #pool = "hikaricp" 

    default.driver = org.postgresql.Driver 
    default.url = "jdbc:postgresql://127.0.0.1:5432/mydbname" 
    default.username = "postgres" 
    default.password = "123456" 
    #default = "default" 

    default.jndiName=ReadWriteDS 
} 

Der Fehler mit und ohne Pool Konfigurationsschlüssel aktiviert in application.conf oben:

Ich habe so viele verschiedene Optionen und Kombinationen ausprobiert, ich habe keine Ideen mehr. Google kennt die Fehler nicht einmal. Play hört einfach auf zu arbeiten und ich muss es neu starten. Versuchen

      dataSource { 
       serverName = localhost 
       databaseName = "mydbname" 
       user = "postgres" 
       password = "123456"
