Vil*_*lla 4 generated-code assisted-inject dagger-2
我尝试在我的项目中AssistedInject使用 Dagger 2 ( https://github.com/square/AssistedInject ) 实现 Jake Wharton 的。
错误:找不到符号@dagger.Module(包括= {InflationInject_ViewModule.class})
生成的代码似乎ViewModule不知道在哪里可以找到InflationInject_ViewModule:
@InflationModule
@Module(includes = [InflationInject_ViewModule::class])
abstract class ViewModule

我的 build.gradle 的相关部分是
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
android {...}
dependencies {
implementation "com.google.dagger:dagger-android:2.16"
implementation "com.google.dagger:dagger-android-support:2.16"
kapt "com.google.dagger:dagger-compiler:2.16"
kapt "com.google.dagger:dagger-android-processor:2.16"
implementation 'com.squareup.inject:inflation-inject:0.3.0'
kapt 'com.squareup.inject:inflation-inject-processor:0.3.0'
}

我已经检查过它InflationInject_ViewModule确实存在于生成的代码中(at build/generated/source/kapt/devDebug/com/project/di/,所以可能与编译器查找源集/生成的代码的位置有关。
有什么建议么?

我使用 AssistedInject ,面临同样的问题。就我而言,事实证明我的(或你的)代码没有任何问题,这是 kapt 问题。
如果您使用某些需要 kapt 的库(例如 room、数据绑定),这些库可能会在 AssistedInject 之前进行处理。
类似于: databinding -> room -> AssistedInject
如果 room 编译失败,AssistedInject 永远不会编译,因此不会生成InflationInject_ViewModule.java
错误示例:

结论:检查项目中需要注释处理器的其他库。确保他们的设置正确。
