Dagger 2 class component not generated

Question

i am facing issue from last 2 days. Currently , i am using Android studio Giraffe version. i am unable to get daggerComponent class. here is my code .

---

this is my app level gradle file

`      plugins {   
        id("com.android.application")    
            id("org.jetbrains.kotlin.android")    
          id("kotlin-android")        
        id("kotlin-kapt")        
           }


   android {    
       namespace = "com.example.myapplication"    
      compileSdk = 34

 defaultConfig {

  applicationId = "com.example.myapplication"
  minSdk = 24
  targetSdk = 34
  versionCode = 1
  versionName = "1.0"

    testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
}

kapt{
    generateStubs=true
}

buildTypes {
    release {
        isMinifyEnabled = false
        proguardFiles(
            getDefaultProguardFile("proguard-android-optimize.txt"),
            "proguard-rules.pro"
        )
    }
}
compileOptions {
    sourceCompatibility = JavaVersion.VERSION_1_8
    targetCompatibility = JavaVersion.VERSION_1_8
}
kotlinOptions {
    jvmTarget = "1.8"
  }

}

dependencies {

implementation("androidx.core:core-ktx:1.12.0")
implementation("androidx.appcompat:appcompat:1.6.1")
implementation("com.google.android.material:material:1.9.0")
implementation("androidx.constraintlayout:constraintlayout:2.1.4")
testImplementation("junit:junit:4.13.2")
androidTestImplementation("androidx.test.ext:junit:1.1.5")
androidTestImplementation("androidx.test.espresso:espresso-core:3.5.1")

kapt ("org.jetbrains.kotlinx:kotlinx-metadata-jvm:0.7.0")


implementation("com.google.dagger:dagger:2.48")
implementation("com.google.dagger:dagger-android:2.48")
implementation("com.google.dagger:dagger-android-support:2.48")

annotationProcessor("com.google.dagger:dagger-compiler:2.48")

 //    kapt ("com.google.dagger:dagger-compiler:2.48")

annotationProcessor("com.google.dagger:dagger-android-processor:2.48")
kapt("com.google.dagger:dagger-android-processor:2.48")

compileOnly("org.glassfish:javax.annotation:10.0-b28")

 //    implementation("org.jetbrains.kotlin:kotlin-stdlib-jre7:1.9.0")

compileOnly("javax.annotation:jsr250-api:1.0")
implementation("javax.inject:javax.inject:1")

}`

NOTE:- those dependencies which i did comment is actually showing me error while rebuild.

Here is my Project level gradle file

`// Top-level build file where you can add configuration options common to all sub-projects/modules. plugins {   
    id("com.android.application") version "8.1.1" apply false 
    id("org.jetbrains.kotlin.android") version "1.9.0" apply false 
   }`

and Here is my component interface

@Singleton
@Component(modules = \[NetworkModule::class\])
interface ApplicationComponent {

    fun inject(mainActivity: MainActivity)

}

and this is the class where i want to call DaggerComponent class

class FakerApplication : Application() {

    lateinit var applicationComponent: ApplicationComponent
    
    override fun onCreate() {
        super.onCreate()
    
    
    }

}

I have tried all stackoverflow's answer but not getting any benefit. whenever i am trying to implement kapt dependency it is showing me error. help me to resolve this issue. Thankyou

From the README.md printed on https://github.com/google/dagger, in the Gradle section's Notes:

For Kotlin projects, use kapt in place of annotationProcessor.

The Gradle file in your question contains both annotationProcessor and kapt lines for both com.google.dagger:dagger-compiler:2.48 and com.google.dagger:dagger-android-processor:2.48. As in this question, your build will work fine for both Java and Kotlin if you use just the kapt lines instead of annotationProcessor lines for both dagger-compiler and dagger-android-processor.

There might be other reasons that your build is failing, and pasting your error message into your question may help with further diagnosis. However, in any case, you are not intended to include both the annotationProcessor and kapt lines for the same processor.

Note for future readers: As of September 2023, kapt is in maintenance mode, to be replaced by Kotlin Symbol Processing (KSP). Dagger 2.48 is the first release to contain an alpha release of Dagger's KSP processor and corresponding KSP documentation.
