El procesador de anotación de Kotlin genera un error de time de compilation al usar Room con Android Studio 3.0 beta7

Estoy comstackndo un proyecto de Android con Android Studio 3.0 Beta 7, usando Kotlin 1.4-2 y Room Persistence Library 1.0.0-beta1.

Esto es parte de mi file Gradle donde estoy agregando dependencies de habitaciones:

• Canal de puente a una secuencia
• Los files de Kotlin + Dagger 2: Dagger * no generarán
• Android WebView salta a la cima en cada actualización de página (?)
• ¿Cómo implementar readLine () !!. ToIntArray () en Kotlin?
• ¿Por qué esta class se considera final?

implementation "android.arch.persistence.room:runtime:1.0.0-beta1" kapt "android.arch.persistence.room:compiler:1.0.0-beta1" 

Mientras estoy comstackndo recibo el siguiente error:

Advertencia: advertencia: versión de origen compatible 'RELEASE_7' del procesador de anotación 'android.arch.persistence.room.RoomProcessor' less que -source '1.8'

Después de agregar indicadores stacktrace / debug para comstackr opciones, este es el error que obtengo:

Limpiar / rebuild no ayuda. ¿Qué podría estar causando este error? La solución temporal parece replace "kapt" con "anotaciónProcesador" estándar, rebuild y luego volver a comstackr con "kapt". Pero después de más cambios en el proyecto, el error sigue apareciendo.
