@Target(
    AnnotationTarget.FIELD,
    AnnotationTarget.FUNCTION,
    AnnotationTarget.PROPERTY_GETTER,
    AnnotationTarget.PROPERTY_SETTER
)
annotation class FieldName(
    val value: String
)

data class UserEntity(
    @FieldName("userName") val userName: String
)

somehow UserEntity::userName.annotations return an empty list. What did I do wrong?

You're missing AnnotationTarget.PROPERTY. Without it the annotation is set on the Java field instead of Kotlin property:
println(UserEntity::class.java.declaredFields.find { it.name == "userName"}?.annotations?.map { it.annotationClass.jvmName })

I tried to add AnnotationTarget.PROPERTY, UserEntity::userName.annotations still return an empty list

I think I might discover a bug

[Czar]

Looks like it's working for you too. What bug?
Also, why do you annotate annotation's own value with itself?

[Czar]

Oh, I think you have put EntityA's annotation by mistake onto the annotation itself, and then EntityB's annotation onto EntityA 🙂

sorry my mistake
