问dagger @IntoSet在kotlin对象中不起作用？

EN

@Module
object MyModuleA {
    @Provides
    @IntoSet
    fun provideOneString(): String {
        return "ABC"
    }
}

@Module
object MyModuleB {
    @Provides
    @ElementsIntoSet
    fun provideSomeStrings(): Set<String> {
        return HashSet<String>(Arrays.asList("DEF", "GHI"))
    }
}

@Component(modules = [ MyModuleA::class, MyModuleB::class])
interface MyComponent {
    fun strings(): Set<String>
}

@Test
fun testMyComponent() {
    val myComponent = DaggerMyComponent.builder().build()
    println("${myComponent.strings()}")
}

@Module
class MyModuleA {
    @Provides
    @IntoSet
    fun provideOneString(): String {
        return "ABC"
    }
}

@Module
class MyModuleB {
    @Provides
    @ElementsIntoSet
    fun provideSomeStrings(): Set<String> {
        return HashSet<String>(Arrays.asList("DEF", "GHI"))
    }
}
