任何处理器都无法识别以下选项：'[kapt.kotlin.generated, room.incremental]'

发布于10月03日

:app:kaptDebugKotlin
w: warning: The following options were not recognized by any processor: '[kapt.kotlin.generated, room.incremental]'

Why am I getting this? I am using Room in a multi module project.

共享库模块: api "androidx.room:room-runtime:$room_version" api "androidx.room:room-ktx:$room_version" api "androidx.room:room-rxjava2:$room_version"个

应用程序模块:

kapt "androidx.room:room-compiler:$room_version"个

格雷德尔.属性

kapt.incremental.apt=true

Build.gradle defaultConfig includes these compile options:

javaCompileOptions {
        annotationProcessorOptions {
            arguments = ["room.incremental":"true"]
        }
    }

推荐答案

这种类型的问题可能发生在已添加到文件室的多模块项目中.对于这样的项目，问题是由于将RoomDatabase派生类添加到库模块中，但配置了构建.应用程序模块的渐变.

解决方案是配置包含RoomDatabase派生类的模块的build.gradle.

In the build.gradle file in the dependencies{} section add the dependency for the room compiler.

kapt "android.arch.persistence.room:compiler:$room_version"

请注意，对于基于java的项目，请使用以下代码

annotationProcessor "android.arch.persistence.room:compiler:$room_version"
