Hi guys!
I know this may seem a bit crazy, but is it possible to get the KSType here corresponding to FirstType and SecondType?
I am able to get the KSType corresponding to AbcType , but not the other two.

ExternalModuleDestinations is an annotation class ExternalModuleDestinations<T: SomeType> and ExternalDestination is also annotation class ExternalDestination<T: OtherType>.

@ExternalModuleDestinations<AbcType>(
        overriding = [
            ExternalDestination<FirstType>(),
            ExternalDestination<SecondType>(),
        ]
    )
    class SomeClass

When I try, I just get T, not the actual types used here (FirstType and SecondType)

Can you try to read the annotation value of ExternalModuleDestinations ?

[Rafael Costa]

Hmm how exactly do I do that? 😅
Sorry I’m not familiar with the term

[Jiaxiang]

say you got the KSClassDeclaration of SomeClass, you can get the list of its annotations via KSClassDeclaration.annotations, iterate through the annotation list, find the annotation with type ExternalModuleDestinations, read the annotation values by KSAnnotation.arguments

[Rafael Costa]

Im afk now, but I think that’s what I’m doing, yes.
Then I get the argument “overriding” and I get an ArrayLisf<KSAnnotation>.
Then I try to get the type argument with something like (will confirm shortly) annotationType.arguments.first().resolve()

[Rafael Costa]

I think I’m missing something there, I’ll check it in 5 min

[Jiaxiang]

don’t resolve, by resolving you get the declaration of the types, which surely only contains type parameter.

[Rafael Costa]

so this is what I actually do (sorry)

it.annotationType.resolve().arguments.first().type!!.resolve()

ìt is a KSAnnotation from the ArrayList<KSAnnotation> I got from "overriding" argument.

[Rafael Costa]

if I don't resolve then I get a KSTypeReference .. how can I convert that into KSType ?

[Rafael Costa]

I guess I would expect to get T if I was using declaration , like:

it.annotationType.resolve().declaration.typeParameters.first()

Since then I was actually going to the declaration of the annotation type (ExternalDestination )

[Rafael Costa]

also, I use the exact same code to get the type argument of @ExternalModuleDestinations<AbcType>. In that case I do get AbcType with

ksAnnotation.annotationType.resolve().arguments.first().type!!.resolve()

[Rafael Costa]

I get that in this case it is actually annotating, while on the other case I'm passing an "instance" of the annotation class to the "overriding" argument.

[Rafael Costa]

@Jiaxiang sorry to tag you, but if you could follow up on this 🙏
I already have a workaround, but I'm still interested in improving things if this is possible.

[Jiaxiang]

sorry, your case might be a little bit convoluted to be communicated via chat, can you put your case in a mini repository so I can take a look?
