Dagger-2未在KOTLIN中生成静态组件类-Android

Question

我正在使用Dagger-2在KOTLIN中生成静态组件类。这是我正在使用的类，但是在创建项目时，无法生成静态组件类：

import javax.inject.Inject


    class Car @Inject constructor(engine: Engine,wheel: Wheel){


        var isCarReady = "Now Car is Ready Vroom!!!!"+engine.isEngineIsReady+wheel.isWheelIsReady


    }


import javax.inject.Inject

class Engine @Inject constructor(){
     val isEngineIsReady = "Engine is ready"


}


import javax.inject.Inject

class Wheel @Inject constructor() {

    var isWheelIsReady = "Wheel is Ready"

}

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import com.abhijit.simpledagger2demo.depedencies.Car
import javax.inject.Inject

class MainActivity : AppCompatActivity() {

    @Inject lateinit var car : Car

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    }
}

import com.abhijit.simpledagger2demo.MainActivity
import dagger.Component

@Component
interface MakeCarComponent {

    fun inject(activity: MainActivity)


}

这里在我的build.gradle下面

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.abhijit.simpledagger2demo"
        minSdkVersion 15
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

    kapt {
        generateStubs = true
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.core:core-ktx:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

    //add dagger dependencies
    // Dagger Android
    kapt "com.google.dagger:dagger-android-processor:2.15"
    implementation "com.google.dagger:dagger-android:2.15"
    implementation "com.google.dagger:dagger-android-support:2.15"


}

不是创建DaggerMakeCarComponent。知道我在这里缺少什么吗？

Answer 1

我发现您缺少build.gradle中的一个依赖项。

  kapt "com.google.dagger:dagger-android-processor:2.15"
    implementation "com.google.dagger:dagger-android:2.15"
    implementation "com.google.dagger:dagger-android-support:2.15"

最后只剩一个

kapt 'com.google.dagger:dagger-compiler:2.15'

它应该起作用，如果您遇到任何问题，请告诉我
