KSP with micronaut 4.2.2: @Client annotated class not introspected when use also @Generated annotation

[altro3]

look to the screenshot:

At the top you see what kapt generated: 2 packages - io.micronaut.openapi.test.api and io.micronaut.openapi.test.model

Next you see generated sources yt micronaut openapi and introspected class by KSP. As you see, generated 2 packages, but introspected only one - io.micronaut.openapi.test.model.

That's because introspection lost all interfaces from package io.micronaut.openapi.test.api

With micronaut 4.2.1 all works fine

Sample interface which lost:

@Generated("io.micronaut.openapi.generator.KotlinMicronautClientCodegen")
@Client("\${openapi-micronaut-client-base-path}")
interface PetApi {

    @Post("/pet")
    fun addPet(
        @Body @Nullable @Valid body: Pet?
    ): Mono<Void>
}

Version

4.2.2

@dstepanov hi! Look to this, pls. This is critical bug for micronaut with KSP

[dstepanov]

No sure what would cause that, going to check next week

@dstepanov Hi! You know, this is certainly a strange error, but I was able to figure it out.

So, the problem is NOT with the interfaces, but with... the @Generated annotation!!!

To reproduce it you need to create an interface, for example:

@Generated("io.micronaut.openapi.generator.KotlinMicronautClientCodegen")
@Client("openapi-micronaut-client-base-path")
interface PetApi {

    /**
     * {@summary Add a new pet to the store}
     *
     * @param body Pet object that needs to be added to the store (optional)
     * @return Mono<Void>
     */
    @Post("/pet")
    fun addPet(
        @Body @Nullable @Valid body: Pet?
    ): Mono<Void>
}

We run the build and see this:

As you can see, there is no class for PetApi in the generated folder, it’s as if the @client annotation was simply ignored

Next, remove the Generated annotation and run clean build again:

As you can see, we now see the generated classes PetApi$Intercepted, $PetApi$Intercepted$Definition and others.

To reproduce this bug you just can add @Generated annotation to PetClient in test-suite-kotlin-ksp:

Ah right, we have a check that was skipping processing classes with Generated annotations. And I have noticed that it was incorrect and fixed it, now we have this. I guess it needs to be removed

[dstepanov]

What is the full name of that @Generated annotation?

@dstepanov jakarta.annotation.Generated
