Is there any way to disable mangling for functions...

Is there any way to disable mangling for functions that consume inline classes?
Spring Data cant deal with this.

https://kotlinlang.org/docs/inline-classes.html#calling-from-java-code but it's not really usable with inheritance (without further hacks), so hopefully that's not the case you're in

[Mikhail]

Oh, I forgot about @JvmName , TYSM!

[Mikhail]

Well, I get '@JvmName' annotation is not applicable to this declaration

And here is my code:

@Repository
interface WebhookRepository : JpaRepository<Webhook, WebhookId> {

    @JvmName("findWebhookByName")
    fun findWebhookByName(name: WebhookId): Optional<Webhook>
}

[ephemient]

yes, because of the issue I linked

[ephemient]

there isn't a good solution

[Mikhail]

Is there any?

[ephemient]

you can @Suppress the error away, but you have to manually use the correct @JvmName on every overload (otherwise you get missing methods at runtime… this is why it's a compiler error)

[Mikhail]

I'm not implementing this interface, Spring does. I'll try what you suggested

[ephemient]

if it's only implemented from the Java side then

@Repository
interface WebhookRepository : JpaRepository<Webhook, WebhookId> {
    @Suppress("INAPPLICABLE_JVM_NAME")
    @JvmName("findWebhookByName")
    fun findWebhookByName(name: WebhookId): Optional<Webhook>
}

should be sufficient

[ephemient]

if it's ever implemented in Kotlin you must remember to manually add @Suppress("INAPPLICABLE_JVM_NAME") @JvmName("findWebhookByName") to the override

[Mikhail]

It's implemented via codegen 🧌 by Spring Data

[Mikhail]

Well, it worked perfectly. Thank you again.
I'll open an issue about it, maybe Spring Data team find a way to be tolerant to Kotlin's function mangling while method name parsing

[ephemient]

if they're using APT for codegen then there's not much they can do about it - there's no way to represent the mangled names in the Java model

[ephemient]

if they're doing it with proxies at runtime or similar, then yeah it could be doable

[Mikhail]

Yeah, they use cglib
