Reflect compiler not generating default builder class.

[Laimiux]

By default, dagger-compiler generates a default Builder class.

With setup such as this:

interface Host {
  fun myDependency(): MyDependency
}

@Component(dependencies = [Host::class])
interface MyFeatureComponent {
  fun feature(): MyFeature
}

there will be a generated method

DaggerMyFeatureComponent.builder().dependencies(myDependencies).build()

We have a bunch of ignored functional tests for the same reason:

  // TODO reflect-compiler bug! Not generating builder method.
  exclude 'dagger/functional/builder/BuilderTest.java'
  exclude 'dagger/functional/cycle/DoubleCheckCycleTest.java'
  exclude 'dagger/functional/membersinject/MembersInjectionOrderingTest.java'
  exclude 'dagger/functional/nullables/NullabilityTest.java'
  exclude 'dagger/functional/MultibindingTest.java'
  exclude 'dagger/functional/NonComponentDependencyTest.java'

Is there any workaround that can be used in the meantime for this? Can I provide the dependencies some other way?

My setup is roughly like this:

@Component(modules = [ FooModule::class ])
interface MyComponent { ... }

@Module
class FooModule(private val myInjectedActivity: BaseInjectedActivity) { ... }

abstract class BaseInjectedActivty {
  override fun onCreate(...) {
    val myComponent = DaggerMyComponent.builder().fooModule(FooModule(this)).build()
  }

We declared @Component.Factory interface to workaround.

Hi @Laimiux , would you share how you used @Component.Factory to work it around?

You have to explicitly declare a factory

@Component(dependencies = [Host::class])
interface MyFeatureComponent {
  @Component.Factory
  interface Factory {
    fun create(host: Host): MyFeatureComponent
  }

  fun feature(): MyFeature
}

Thank you!
