Dagger 2 doesnt generate code. Unresolved reference: DaggerAppComponent

I have been trying to generate code in project for a week. The problem is that after i added AppComponent, Module, dependencies and plugin it doesnt work. I got compilation error. Then i repeated all this in new empty project an it works properly. My Android Gradle plugin version:7.1.0 Gradle version:7.3

My AppComponent

@Component(modules = [AppModule::class]) interface AppComponent { fun mainRepository(): MainRepository }

AppModule

@Module object AppModule {

@Provides
fun provideMainRepository(): MainRepository {
    return MainRepository()
}

}

Gradle file

plugins {
id 'com.android.application'
id 'kotlin-android'
id 'com.google.gms.google-services'
id 'kotlin-kapt'
id 'com.google.firebase.crashlytics'
id 'kotlin-parcelize'

}

android { compileSdkVersion 31 buildToolsVersion "30.0.3"

defaultConfig {
    applicationId "com.flametech.vaytoday"
    minSdkVersion 22
    targetSdkVersion 30
    versionCode 58
    versionName "2.19"
    multiDexEnabled = true
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

buildFeatures {
    viewBinding = true
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}
compileOptions {
    sourceCompatibility JavaVersion.VERSION_11
    targetCompatibility JavaVersion.VERSION_11
}
kotlinOptions {
    jvmTarget = '11'
}

}

AppComponent creating in MainActivity

   override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    val appComponent: AppComponent = DaggerAppComponent.create()}

SOLUTION!!! The problem is solved. I checked my dependencies and understood that i had import in my AppComponent and in my Module like this import com.google.android.datatransport.runtime.dagger.Component

But the right import was import dagger.Component
