automatic class is not generated

i just followed the tutorials here and trying to make an android app I made a module class and a component interface and also wrote all the annotations related too classes and objects for them but still the class Daggercomponent is not generated for me
also added all 4 lines of code to dependencies in app gradle
whats the problem ?(i tried to find annotation processor option in android studio 3.1.2 but its no where to be found)

component

`@Singleton
@Component (modules = [globals::class])
interface component {

fun inject (activity:Activity)

}`

module

`@Module
class globals {

lateinit var volleyinstance:VolleyController

fun golobals(volley:VolleyController){

volleyinstance=volley

}

@Provides
@Singleton
fun provideVolley():VolleyController{
return volleyinstance
}

}`

Main class
`class MainActivity : AppCompatActivity() {

@Inject lateinit var volleyController:VolleyController

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
}`
