quarkus: EntityManager is not injected

Describe the bug EntityManager instance is not injected into @ApplicationScoped object so i’m having the following exception for ``:

...
12:02:31,107 ERROR [io.qua.dev.DevModeMain] Failed to start Quarkus: java.lang.ExceptionInInitializerError
...
Caused by: kotlin.UninitializedPropertyAccessException: lateinit property entityManager has not been initialized
...

Expected behavior EntityManager instance is injected and ready -to-use, no exception are thrown

Actual behavior during ./mvnw compile quarkus:dev i have the following exception

...
12:02:31,107 ERROR [io.qua.dev.DevModeMain] Failed to start Quarkus: java.lang.ExceptionInInitializerError
...
Caused by: kotlin.UninitializedPropertyAccessException: lateinit property entityManager has not been initialized
...

The app is shutdown.

To Reproduce Steps to reproduce the behavior:

git clone git@github.com:4ntoine/NotesServerApp.git
cd NotesServerApp
git checkout 32c8240dfd6672471cdd73f613e092522fb6528e
./gradlew publishToMavenLocal
cd app-quarkus
./mvnw compile quarkus:dev

Configuration

quarkus.datasource.url = jdbc:h2:mem:notes
quarkus.datasource.driver = org.h2.Driver

# drop and create the database at startup (use `update` to only update the schema)
quarkus.hibernate-orm.database.generation=drop-and-create

It turns out to be a problem with how CDI is being used in the supplied code:

If you use something like:

@ApplicationScoped
open class QuarkusEntityManagerFactory {
    @Inject
    lateinit var entityManager: EntityManager
}

@ApplicationScoped
open class Configuration {

    @Produces
    open fun getJpaGateway(entityManagerFactory: QuarkusEntityManagerFactory): JpaGateway {
        val mapper = MapperImpl()
        return JpaGateway(entityManagerFactory.entityManager, mapper)
    }

    @Produces
    open fun getAddNoteUseCase(gateway: JpaGateway) = AddNoteImpl(gateway)

    @Produces
    open fun getListNotesUseCase(gateway: JpaGateway): ListNotes = ListNotesImpl(gateway)
}

everything works as expected.

Note that you can simplify things even more by removing QuarkusEntityManagerFactory completely and using something like:

    @Produces
    open fun getJpaGateway(entityManager: EntityManager): JpaGateway {
        val mapper = MapperImpl()
        return JpaGateway(entityManager, mapper)
    }

So I’m going to go ahead and close this since it’s not a Quarkus bug. If you feel that this resolution is not correct, feel free to reopen and add more information.

Thanks
