I’m baffled. And the bytecode viewer is not helping because it throws an exception 🙂

My bytecode viewer shows that only constructor param annotated

but it’s a

val

, shouldn’t it be present somewhere in the class as well, either as a field or property?

@field:Json

annotates field explicitly

Yes I know that works, I just don’t want to import this on users, it should be possible to do without

Not sure about annotation application strategy by default

The target is a compile time check only, my code wouldn’t compile otherwise

Oh, yeah

yup

I suppose you can get property annotation using kotlin-reflect

The code I pasted above wouldn’t compile without it 🙂

Okay, got it

The target is not check only. It drives where it is applied via some rules.

I mean a runtime look up cannot fail because the target is wrong since your code wouldn’t even have compiled if the target was wrong

@cedric Works for me with memberProperties instead of declaredMemberProperties

Interestingly, I also observed that

Hmm, nope doesn’t work. Probably worked for me only with explicit @property:Json

Wow you’re right, removing that target makes

val ann = it.findAnnotation<Json>()

work.

Still looks like a bug, or there is some not obvious reason for that

That’s my assessment too, hence why I summoned Roman 🙂

Maybe make sense to create an issue

Yes I will

Also, this is not an kotlin-reflect problem. because I don’t see synthetic accessor for property annotations in byte code of class if annotation contains AnnotationTarget.VALUE_PARAMETER

Yeah, added a comment
