define a alias of annotation

Compiler version

If you're not sure what version you're using, run print scalaVersion from sbt
(if you're running scalac manually, use scalac -version instead).
3.3.1

Minimized code

package com.nxin.product.domain

import org.axonframework.modelling.command.TargetAggregateIdentifier
import scala.annotation.meta.getter

type JLong = java.lang.Long
type JList[T] = java.util.List[T]
type JInt = java.lang.Integer
type JBool = java.lang.Boolean
type JMap[K, V] = java.util.Map[K, V]

type aggregateId = TargetAggregateIdentifier @getter

Output

[Error] C:/Users/petzold/IdeaProjects/product-center/product-center-domain/src/main/scala/com/nxin/product/domain/PreDef.scala:12:20: Cyclic reference involving val
[Error] C:/Users/petzold/IdeaProjects/product-center/product-center-domain/src/main/scala/com/nxin/product/domain/PreDef.scala:3:12: value axonframework is not a member of com.nxin.product.domain.org

// TODO add output here

Expectation

then i change my code to

package com.nxin.product.domain

import scala.annotation.meta.getter

type JLong = java.lang.Long
type JList[T] = java.util.List[T]
type JInt = java.lang.Integer
type JBool = java.lang.Boolean
type JMap[K, V] = java.util.Map[K, V]

type aggregateId = org.axonframework.modelling.command.TargetAggregateIdentifier @getter

and use it

it report another error

Is this something that worked in an earlier version? It seems to me that the latter error is valid: an annotated type of the form C @annot does not have a constructor, and therefore cannot be used as an annotation itself. Only C has a constructor.

the earlier version is scala 2.13, i'm trying to upgrade to scala 3.3.1 the error appear

[cjdxhjj]

the first version report the error 'Cyclic reference involving val' and 'value axonframework is not a member of com.nxin.product.domain.org', why?

[cjdxhjj]

the TargetAggregateIdentifier definition is

[cjdxhjj]

the command id must decorate the TargetAggregateIdentifier annotation at field

that work on scala 2.13
