Cannot Find Symbol DaggerApp_HiltComponents_SingletonC.builder()

Need help.

Am building my multi-module project with Dagger-Hilt. Am getting this error:

/HiltDemo/app/build/generated/source/kapt/debug/com/app/hilt/Hilt_App.java:22: error: cannot find symbol
      return DaggerApp_HiltComponents_SingletonC.builder()
             ^
  symbol: variable DaggerApp_HiltComponents_SingletonC

Here’s the generated file with the error:

/**
 * A generated base class to be extended by the @dagger.hilt.android.HiltAndroidApp annotated class. If using the Gradle plugin, this is swapped as the base class via bytecode transformation.
 */
@Generated("dagger.hilt.android.processor.internal.androidentrypoint.ApplicationGenerator")
public abstract class Hilt_App extends SplitCompatApplication implements GeneratedComponentManagerHolder {
  private final ApplicationComponentManager componentManager = new ApplicationComponentManager(new ComponentSupplier() {
    @Override
    public Object get() {
      return DaggerApp_HiltComponents_SingletonC.builder()
          .applicationContextModule(new ApplicationContextModule(Hilt_App.this))
          .build();
    }
  });

  @Override
  public final ApplicationComponentManager componentManager() {
    return componentManager;
  }

  @Override
  public final Object generatedComponent() {
    return this.componentManager().generatedComponent();
  }

  @CallSuper
  @Override
  public void onCreate() {
    // This is a known unsafe cast, but is safe in the only correct use case:
    // App extends Hilt_App
    ((App_GeneratedInjector) generatedComponent()).injectApp(UnsafeCasts.<App>unsafeCast(this));
    super.onCreate();
  }
}

Hey @PykeChen Try adding this into gradle.properties

kapt.use.worker.api=false kapt.incremental.apt=false

Since adding api instead of implementation is not an option for us for our core module, I had to put some of the required libraries in both app and core module.
