Android 景观客房 - Kotlin Gradle 找不到 DSL 方法：'kapt()'

Question

https://codelabs.developers.google.com/codelabs/android-room-with-a-view-kotlin/index.html?index=..%2F..index#2

找不到 Gradle DSL 方法："kapt((" 可能的原因：项目 "Kotlin First Class"可能使用的是Android Gradle的一个版本 不包含该方法的插件(例如，添加了"testCompile" 在 1.1.0 中(。将插件升级到版本 3.5.3 并同步项目

"Kotlin First Class"项目可能正在使用 Gradle 的一个版本 不包含该方法。打开 Gradle 包装器文件

构建文件可能缺少 Gradle 插件。应用 Gradle 插件
