kotlin与dagger2问题:Unresolved reference: DaggerMainComponent

kotlin项目集成dagger2时遇到:

E:\Users\lenovo\MyDagger2\app\src\main\java\com\xq\mydagger2\MainActivity.kt
Error:(22, 9) Unresolved reference: DaggerMainComponent
Error:Execution failed for task ':app:compileDebugKotlin'.
> Compilation error. See log for more details

查看gradle console:

Parallel execution with configuration on demand is an incubating feature.
app: 'androidProcessor' dependencies won't be recognized as kapt annotation processors. 
Please change the configuration name to 'kapt' for these artifacts:
 'com.google.dagger:dagger-compiler:2.10' 
and apply the kapt plugin: "apply plugin: 'kotlin-kapt'".

解决:

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.xq.mykotlin"
        minSdkVersion 14
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    configurations.all {
        resolutionStrategy.force 'com.android.support:support-annotations:26.1.0'
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
	
	implementation 'com.google.dagger:dagger:2.17'
	annotationProcessor 'com.google.dagger:dagger-compiler:2.17'	
	//java中用annotationProcessor
}

改成:


apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

apply plugin: 'kotlin-kapt'				//添加

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.xq.mydagger2"
        minSdkVersion 14
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }


    configurations.all {
        resolutionStrategy.force 'com.android.support:support-annotations:26.1.0'
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    implementation 'com.google.dagger:dagger:2.17'
//    annotationProcessor 'com.google.dagger:dagger-compiler:2.17'
    kapt 'com.google.dagger:dagger-compiler:2.17'		
    //将annotationProcessor改成kapt
	//kotlin用kapt
}
