• Kotlin Plugin up to date?
• Gradle Plugin up to date?
• Kotlin version up to date?
• only use kapt for annotation processing (don't mix Android Studio's annotationProcessor, apt and kapt, or any other processor)
• use kapt3 by using apply plugin: 'kotlin-kapt'
• don’t use kapt { generateStubs true } } at all, it will not work with kapt3
• using databinding? then databinding compiler version needs to be the same as gradle plugin version ( kapt "com.android.databinding:compiler:$version")

Additionally, I stick to org.jetbrains.kotlin:kotlin-stdlib and don’t use the jre7 version
