我在我的
Android应用程序中使用dagger2.即使没有错误,它也不会生成匕首组件类.
我在设置中启用了注释处理器并重新启动我的android工作室,但这对我不起作用.我也读了这个线程Dagger2 not generating Daggercomponent classes,并在一个不推荐使用apt的线程上阅读,所以我使用的是annotationProcessor
基本模块build.gradle
apply plugin: 'com.android.feature' apply plugin: 'kotlin-android' apply plugin: 'kotlin-kapt' android { compileSdkVersion 26 buildToolsVersion "26.0.1" baseFeature true defaultConfig { minSdkVersion 23 targetSdkVersion 26 versionCode 1 versionName "0.0.1" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro' } } } dependencies { application project(':app') feature project(":main") feature project(":tv") api 'com.android.support:appcompat-v7:26.0.2' api 'com.android.support.constraint:constraint-layout:1.0.2' api 'com.android.support:design:26.0.2' api "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" api "org.jetbrains.anko:anko-commons:$anko_version" api "android.arch.lifecycle:runtime:1.0.0-alpha9" api "android.arch.lifecycle:extensions:1.0.0-alpha9" kapt "android.arch.lifecycle:compiler:1.0.0-alpha9" api 'com.squareup.retrofit2:retrofit:2.3.0' api "com.squareup.retrofit2:converter-moshi:2.0.0" api 'com.google.dagger:dagger:2.11' kapt 'com.google.dagger:dagger-compiler:2.11' api 'com.github.bumptech.glide:glide:4.0.0' kapt 'com.github.bumptech.glide:compiler:4.0.0' // new version 1.5.2 has some multi dex issue debugApi 'com.squareup.leakcanary:leakcanary-android:1.5.1' releaseApi 'com.squareup.leakcanary:leakcanary-android-no-op:1.5.1' } repositories { mavenCentral() } apply plugin: 'com.google.gms.google-services'
电视功能build.gradle

项目build.gradle

NetComponent.kt
@Component(modules = arrayOf(AppModule::class,NetModule::class)) interface NetComponent { fun inject(activity: MainActivity) }
解决方法
您的模块是即时应用功能模块.而且看起来kapt还不支持那些.
>功能模块
>图书馆模块dagger kapt
将所有内容从功能模块移动到库模块.然后使功能模块依赖于库模块.
图书馆模块确实支持kapt.
This sample project在Instant App Feature模块中使用Dagger和Kapt,它开箱即用.您的项目设置必须存在其他问题,这与Dagger或注释处理无关.
通过Instant App Codelab并确保你没有误解任何事情.
然后原来的答案应该有效.
原始答案
使用kapt而不是annotationProcessor配置.如:
kapt "android.arch.lifecycle:compiler:1.0.0-alpha9" kapt 'com.google.dagger:dagger-compiler:2.11' kapt 'com.github.bumptech.glide:compiler:4.0.0'
kapt "com.android.databinding:compiler:3.0.0-beta4"
使用不同的构建插件版本时,不要忘记更新版本.
Kotlin插件没有获取annotationProcessor依赖项,我们必须使用kapt依赖项.
最后,要使用最新版本的Kotlin注释处理器,请将它放在模块的build.gradle顶部:
apply plugin: 'kotlin-kapt'
Kotlin对com.android.feature模块的支持是added in Kotlin 1.1.4,确保你至少使用它.
