ksp 2.1.10-RC-1.0.29

code example:

interface Test {
    val sampleRate: Duration
    interface Factory {
        fun create(sampleRate: Duration) : Test
    }
}
internal class TestImpl @AssistedInject constructor(
    override val sampleRate: Duration
) : Test {

    @AssistedFactory
    interface Factory : Test.Factory {

Once replacing the Duration with an Intit worked.

Where is Test.Factory defined?

At first glance, this seems similar to Kotlin obfuscating internal method names, though your example doesn't use internal. If it's a similar issue, one workaround is to use @JvmName("create") on the create method to try to avoid Kotlin's obfuscation.

[cohenItay]

You are correct my example was written incorrectly.
Iv'e added the internal and the the Factory declaration.

I'll try the create approach, is there any explanation in the docs to it? because I haven't found one

[danysantiago]

You do need to help Dagger which generates Java and use @JvmName so it can invoke functions with inline classes such as kotlin.time.Duration from Java, see: https://kotlinlang.org/docs/inline-classes.html#calling-from-java-code
