Quarkus runtime does not inject EntityManager

Question

I have tried @PersistenceContext, @PersistenceUnit, and @Inject combinations but nothing works. @Inject fails maven-quarkus-plugin build:

[ERROR] Caused by: javax.enterprise.inject.UnsatisfiedResolutionException: Unsatisfied dependency for type javax.persistence.EntityManager and qualifiers [@Default]

I have tried with and without persistence.xml. My datasource and application.properties work fine, as I can just inject a AgroalDataSource and do direct JDBC, but I want to port over my JPA Entity classes and use them.

my parent module pom

Answer 1

I figured it out! Not real "intuitive", but I had not migrated over any Entity classes yet. All it took was to put one class in scope and everything started working. So much for simple prototyping. Maybe it should have warned "no entity classes found".
