Unsatisfied dependency for type io.acme.helpers.OAuth2Helper and qualifiers [@Default]

Question

I am trying to use dependency injection from my own library using Quarkus as the main framework and it's not working out. When I declare the class inside the project, @Inject works exactly as expected. However if I move the class out to a jar and them include that jar - injection fails. I know the class IS visible by the JVM because if I replace the injection with the call to the constructor - the object is created. That is not my acceptable solution because in that case I would be missing other functionality provided by the injection. The class I'm injecting IS annotated with @ApplicationScoped

I'm currently out of ideas what I could be mising.

Answer 1

I resolved my issue by following these steps:

1. Declare exactly one constructor with @Inject
2. Add quarkus.index-dependency..group-id and artifact-id to application properties
3. Adding Jandex maven plugin
