Quarkus multiproject CDI (Kotlin) (solved)

[Ragin-LundF]

Hi,

I tried to create a template for further projects with Quarkus instead of Spring Boot.
We use a swagger-first approach and a separation of different layers with multiple projects.

The current state of the project skeleton can be found at https://github.com/Ragin-LundF/quarkus-multiproject-default

My idea was to create the API interfaces together with the DTOs and add a manual implementation of the REST controllers. Those REST controllers should then use the domain services to execute the logic behind the API endpoint.

Both classes (REST controller and domain service) have the @ApplicationScoped annotation and the controller injects the domain service via constructor:

• https://github.com/Ragin-LundF/quarkus-multiproject-default/blob/main/newproject-domain-services/src/main/kotlin/io/github/ragin_lundf/domain_services/pets/PetDomainService.kt
• https://github.com/Ragin-LundF/quarkus-multiproject-default/blob/main/newproject-rest-api/src/main/kotlin/io/github/ragin_lundf/newproject/impl/pets/PetApiController.kt

But when I try to assemble the application I get this exception:

* What went wrong:

I also tried to use @Inject with a lateinit declaration, but with the same result.

Is there any tipp how to solve this?

Thanks already for your help ;).

I found the solution...

After adding apply(plugin = "org.kordamp.gradle.jandex") to all subprojects it compiled.

[mkouba]

Yes, you need to make sure that all subprojects containing the beans are discovered, as described in the Bean Discovery. A Jandex index META-INF/jandex.idx is one of the ways. A META-INF/beans.xml descriptor is another one.
