           This is a known exception, and Jetifier won't be able to jetify this library.
           Suggestions:
            - If you believe this library doesn't need to be jetified (e.g., if it already supports AndroidX, or if it doesn't use support libraries/AndroidX at all), add android.jetifier.blacklist = {comma-separated list of regular expressions (or simply names) of the libraries that you don't want to be jetified} to the gradle.properties file.
            - If you believe this library needs to be jetified (e.g., if it uses old support libraries and breaks your app if it isn't jetified), contact the library's authors to update this library to support AndroidX and use the supported version once it is released.

经项目全局搜索，Mapbox 中包含了 support-v4-25.1.0.aar 库，该库以 aar 文件的形式出现，不能在 gradle 中使用 gradle implementation 配置，与 AR 中支持的 androidx 库存在冲突。

 

问题原因可以归结为 androidx 和 support-v4-25.1.0 存在冲突。MapBox 使用过时的支持库，捆绑的插件会导致与 AndroidX 冲突。

 

在 gradle 中删除 androidx 的依赖会无法构建包，android.enableJetifier=true （表示针对主工程中使用到的三方库，也会自动执行 AndroidX 的替换过程）注释掉也一样会无法 build 成功。删除 support-v4-25.1.0.aar 会重新导入。

 

1、获取 Jetifier。https://developer.android.com/studio/command-line/jetifier

 

独立的 Jetifier 工具可将依赖于支持库的库迁移为依赖于等效的 AndroidX 软件包依赖。该工具可让您直接迁移单个库，而无需使用 Android Studio 附带的 Android Gradle 插件。

其工作原理就是将 jar 或 aar 中的 support 依赖自动改为 androidx 依赖。当然也可以逆转。使用该方法，就无需使用 android studio 的 gradle 来进行迁移了。

 

2、解压并配置到系统环境变量。

 

3、Run this command：
