Failed to execute goal deploy

Question

I'm using JBOSS EAP-7.3.0 Java 9 in IntelliJ the remaining classes which are displayed in the error are created by default. So will just focus on the class MessageRepository .

The commands mvn clean and mvn install run successfully but mvn wildfly:deploy yields the following error:

How can I fix this error?

Answer 1

By default a EntityManager is not injectable. You need to create a producer if you want to inject an EntityManager . Something like the following.

public class Resources {

    @Produces
    @PersistenceContext
    private EntityManager entityManager;

}

Your other option is to not use @Inject and use @PersistenceContext instead.
