使用'kotlin-kapt'插件,Android Studio不会提供有关Dagger 2的特定错误

Question

我使用Kotlin和Dagger 2.问题是,当我在实现Dagger时犯了错误(例如,错过@Inject了类约束器)时,IDE并没有特别显示错误的位置.Insead编译器错误总是一样的:

Execution failed for task ':app:kaptDebugKotlin'. Internal compiler error. See log for more details

有故意的类(评论@Inject):

class LoginPresenter //@Inject
constructor(private val request: LoginRequest)

项目build.gradle文件:

buildscript {
    ext.kotlin_version = '1.1.4-3'

    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

模块build.gradle:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"
    defaultConfig {
        applicationId "com.example.kravets_a.kotlinanddagger"
        minSdkVersion 16
        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'
        }
    }
}

dependencies {
    ...

    compile 'com.google.dagger:dagger:2.10'
    annotationProcessor 'com.google.dagger:dagger-compiler:2.10'
    kapt "com.google.dagger:dagger-compiler:2.10"

    compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
}
repositories {
    mavenCentral()
}

选项1

使用apply plugin: 'kotlin-kapt'.当发生错误时,您可以在Android Studio =>右下角=>在Gradle控制台上看到它.

感谢David Medenjak的评论.

选项2

替换apply plugin: 'kotlin-kapt'为kapt { generateStubs = true }

编译失败并带有预期结果:

[com.example.kravets_a.kotlinanddagger.logic.MainActivityComponent.inject(com.example.kotlinanddagger.MainActivity)] com.example.kotlinanddagger.logic.LoginPresenter不能在没有@Inject构造函数或@ Provide-或@Produces的情况下提供注释方法.

像这样的教程,这个或那个说apply plugin: 'kotlin-kapt'可以用来代替kapt { generateStubs = true }.但在这种情况下,Android Studio不提供特定的编译错误.
