我的应用程序现在依赖于protobuf-liteand protobuf-javalite，这会触发重复的类错误。

最近，Firebase Android 已经从旧protobuf-lite的依赖迁移到依赖protobuf-javalite（github 问题| PR 实施更改）。

您需要一起更新受此更改影响的所有 firebase SDK，否则旧 SDK 会将错误的依赖项拉入您的应用程序中。

以下是受影响的 SDK 及其支持版本的列表 protobuf-javalite

- com.google.firebase:firebase-firestore:21.5.0
- com.google.firebase:firebase-inappmessaging:19.1.0
- com.google.firebase:firebase-inappmessaging-display:19.1.0
- com.google.firebase:firebase-config:19.2.0
- com.google.firebase:firebase-abt:19.1.0
- com.google.firebase:firebase-perf:19.0.8

编辑：添加firebase-perf到列表中，因为它依赖于配置并且也需要更新。
