automatic class is not generated

[Moeinh77]

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)
    }`
