使用 Jetifier 工具的 AndroidX 迁移将支持库转换为 RC 版本
AndroidX migration using Jetifier tool converts support libraries to RC versions
在迁移到 Android X 的过程中，tt 似乎 Jetifier 工具将一些第 3 方库转换为 RC 版本 (gradle-4.6)。

有没有我可以强制只采用稳定（固定）版本的解决方案？
嗯，在jetifier源代码中挖掘后，似乎jetifier版本gradle-4.6是alpha10:
/gradle/m2repository/com/android/tools/build/jetifier/jetifier-processor/1.0.0-alpha10/jetifier-processor-1.0.0-alpha10.jar
/gradle/m2repository/com/android/tools/build/jetifier/jetifier-core/1.0.0-alpha10/jetifier-core-1.0.0-alpha10.jar
这个包 jetifier 中的本地映射文件将一些支持库转换为 RC 版本。
添加更新的 jetifier 依赖关系解决了这个问题（顶部 build.gradle）：
classpath 'com.android.tools.build.jetifier:jetifier-core:1.0.0-beta02'
classpath 'com.android.tools.build.jetifier:jetifier-processor:1.0.0-beta02'
