[KSP2] KSValueParameterImpl changes field isVal if class defined in library

[oscarthecat]

kotlin version 2.1.0
ksp version 2.1.0-1.0.28

we have a module1/ConsoleLens.kt, in which we have a

@LensForType(type = Console::class, intoPackage = "com.foobar.blens.test")
interface ConsoleLens

we try to handle @LensForType this annotation in out ksp. It refer another Console class which is defined in module2/Console.kt like

data class Console(
    val brand: String,
    val type: String,
) {
    companion object
}

when our ksp runs we check Console class should be data class and all params in primary constructor should be val, but it failed when using ksp2, while it does work when using ksp1.

In ksp2 if Console.kt is also defined in module1(as -source-roots like ConsoleLens.kt), it also works. It failed to our check when Console.kt is defined in -libraries as a klib, this happen both via gradle build and command line build.

After debug isVal we find in KSValueParameterImpl.kt

    override val isVal: Boolean
        get() = (ktValueParameterSymbol.psi as? KtParameter)?.let { it.hasValOrVar() && !it.isMutable } ?: false

ktValueParameterSymbol (came from -libraries klib) it self isVal is true, but ktValueParameterSymbol.psi is null so finally it returns false.

Any way to get ktValueParameterSymbol.psi non null? or any change should we apply to out ksp2 command? Thanks a lot.

ps out ksp2 command is like
