android - Kotlin 注释处理器在将 Room 与 A​​ndroid Studio 3.0 beta7 一起使用时出现编译时错误

Question

我正在使用 Android Studio 3.0 Beta 7、Kotlin 1.4-2 和 Room Persistence Library 编译 Android 项目1.0.0-beta1。

这是我在其中添加 Room 依赖项的 Gradle 文件的一部分:

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

编译时出现以下错误:

Warning:warning: Supported source version 'RELEASE_7' from annotation processor 'android.arch.persistence.room.RoomProcessor' less than -source '1.8'

将堆栈跟踪/调试标志添加到编译选项后，这是我得到的错误:

Error:org.jetbrains.kotlin.kapt3.diagnostic.KaptError: Error while annotation processing

清理/重建没有帮助。什么可能导致此错误？临时解决方案似乎是用标准的“annotationProcessor”替换“kapt”，重建然后用“kapt”再次构建。但在项目进一步更改后，错误再次出现。

我也在使用 kapt 插件和房间，并且有类似的错误。就我而言，我通过移动这条线 apply plugin: 'kotlin-kapt' 来解决它来自 app build.gradle到top build.gradle ，在 buildscript{} 之外 block ，然后错误就消失了。
