Using @ComponentScan and multiple packages

[dularion]

Expected Behavior

We have some Domains in the src/main/groovy directory, in order to bundle Module code together in a prettier way. For this, we use the annotations @Entity and @Artefact("domain") which works great, as long as we put them in the default application package. However, if we another package, and use @ComponentScan(basePackages = ["package1", "package2"]) the domains are not recognized in the second package, even with the same annotations.

Actual Behaviour

Instead of a functional Entity, when calling the list() command on an Entity from package2, i get this error:

Caused by: java.lang.IllegalStateException: Either class [pms.Foo] is not a domain class or GORM has not been initialized correctly or has already been shutdown. Ensure GORM is loaded and configured correctly before calling any methods on a GORM entity.

Steps To Reproduce

I've added a sample project to this issue. It includes the packages "dila" and "pms". There are two Entities, Foo and Test, of which Test loads fine, but Foo doesnt. To test this, I've added a list command for each in the TestController which can be accessed under http://localhost:8080/test/listFoo and http://localhost:8080/test/listTest

grails-app/init/dila/Application.groovy:

class Application extends GrailsAutoConfiguration {
    static void main(String[] args) {
        GrailsApp.run(Application, args)
    }
}

src/main/groovy/dila/Test.groovy

package dila

import grails.artefact.Artefact
import grails.gorm.annotation.Entity
import grails.validation.Validateable

@Entity
@Artefact("Domain")
class Test implements Validateable {
  String name
}

src/main/groovy/pms/Foo.groovy

package pms

import grails.artefact.Artefact
import grails.gorm.annotation.Entity
import grails.validation.Validateable

@Entity
@Artefact("Domain")
class Foo implements Validateable {
  String name
}

TestController.groovy

package dila

import grails.converters.JSON
import pms.Foo

class TestController {

  def listFoo() {
    render Foo.list() as JSON
  }

  def listTest() {
    render Test.list() as JSON
  }
}

However, if we another package, and use @componentscan(basePackages = ["package1", "package2"]) the domains are not recognized in the second package, even with the same annotations.

Is @ComponentScan relevant to discovering domain classes in Grails 6.2.0?

[dularion]

it is, if they are placed in /src/main/groovy instead of /grails-app/domains

Thank you!

Does @AutoConfigurationPackage work instead of @ComponentScan?
