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:

• Kotlin 1.1.3-2 No se puede crear una instancia de fragment en OnResume Android
• @PostConstruct no se llama cuando se usa Kotlin BeanDefinitionDsl
• ¿Cómo obtengo el post de la identificación del post?
• ¿Cómo hacer reference a "esto" en oyentes anónimos cuando se utiliza notación corta?
• Cómo ejecutar el command bash en Kotlin

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:

Error: org.jetbrains.kotlin.kapt3.diagnostic.KaptError: Error al procesar la anotación

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.
