如何将 Kotlin 文件添加到旧的 android java 项目？

Question

我正在尝试基于 ODK Collect 构建一个 android 应用程序。ODK Collect 应用程序是用 Java 编写的。我想使用 Kotlin 进行开发。我使用 android studio 新活动向导添加了一个基于 Kotlin 的空活动。当我尝试编译时，出现以下错误；

Executing tasks: [:collect_app:assembleDebug]

> Configure project :collect_app

Could not find google-services.json while looking in [src/nullnull/odkCollectRelease, src/odkCollectRelease/nullnull, src/nullnull, src/odkCollectRelease, src/nullnullOdkCollectRelease]

这里有一些事情可以尝试在每个之后重建。让我知道事情的后续。尝试单击工具菜单 -> Kotlin -> 在项目中配置 Kotlin。尝试点击工具菜单 -> Kotlin -> 配置 Kotlin 插件更新尝试添加apply plugin: 'kotlin-kapt'尝试单击文件 -> 使缓存无效/重新启动更新 添加到 build.gradlekapt { generateStubs = true }
