If you use Kotlin, then you have to use kapt instead of annotationProcessor, and must also apply kotlin-kapt plugin.

apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'

dependencies {
    implementation "androidx.lifecycle:lifecycle-extensions:2.0.0-alpha1"
    kapt "androidx.lifecycle:lifecycle-compiler:2.0.0-alpha1"
    implementation "androidx.room:room-runtime:2.0.0-alpha1"
    kapt "androidx.room:room-compiler:2.0.0-alpha1"
