Quarkus dependency app using different persistence unit triggering errors related to EntityManager

Question

I've got the following class inside a primary quarkus application (named dep-repos) I've created:

package com.myapps.dep.common;

@ApplicationScoped
public class DepRepository implements PanacheRepositoryBase<DepEntity, Integer> {

    @Inject
    @PersistenceUnit("dep")
    EntityManager em;

    @Transactional
    public void save(final List<DepEntity> entities) {
        entities.forEach(e -> em.persist(e));
    }
}

that I use this way:

package com.myapps.dep.common;

@ApplicationScoped
public class MyDep {

    @Inject
    DepRepository repository;

    // ...
}

and I use that app as dependency of another quarkus app:

<dependency>
   <groupId>com.myapps<groupId>
   <artifactId>dep-repos</artifactId>
   <version>1.0.0/version>
</dependency>

that I use this way:

package com.myapps.main;

import com.myapps.dep.common.MyDep;

@ApplicationScoped
public class MyServiceImpl implements MyService {

    @Inject
    MyDep myDep;

    // ...
}

and I defined all the required properties inside a application.yml file, where I now have 2 persistence units, one for the main app and the other one releated to the other dep-repos app:

quarkus:
  datasource:
    db-kind: db2
    username: test
    password: test
    jdbc:
      url: jdbc:db2://<url>
    "dep":
      db-kind: db2
      username: test
      password: test
      jdbc:
        url: jdbc:db2://<url>
  hibernate-orm:
    dialect: org.hibernate.dialect.DB2Dialect
    database:
      generation: validate
    packages: com.myapps.main
    "dep":
      datasource: dep
      packages: com.myapps.dep

now, when I build the application:

./mvnw package -Dquarkus.config.locations=file:/./application.yml -Pnative

I get the following errors:

Any idea on how to fix that?

Thanks

I'm not 100% sure how this works, but could you try the following?

@ApplicationScoped
public class DepRepository implements PanacheRepositoryBase<DepEntity, Integer> {

    @Inject
    @io.quarkus.hibernate.orm.PersistenceUnit("dep")
    EntityManagerFactory emf;
    @Inject
    EntityManager em;

    @Transactional
    public void save(final List<DepEntity> entities) {
        entities.forEach(e -> em.persist(e));
    }
}
