androidx jetifier无法转换com.android.tools.common26.4.2

Question

任何人都可以对此提供帮助：

我正在android Studio 3.5.2中编译一个android应用程序（sdk中的所有内容都是最新的）并获得以下链接到应用程序的错误：javaPreCompileDebug：

错误消息是

The given artifact contains a string literal with a package reference 'android.support.design.widget' that cannot be safely rewritten. Libraries using reflection such as annotation processors need to be updated manually to add support for androidx.

如果有人能破译，我在下面附加了一个完整的堆栈跟踪。使用Jetifier转换com.android.tools/common/26.4.2/71f8d5ea1ddb6bfe3fb100e0642262951e11e304/common-26.4.2.jar时，似乎发生了错误。

在我的项目中找不到我正在使用com.android的任何地方。尽管在项目结构/所有模块中都提到了v26.42工具，但我不知道这些参考来自何处：

Answer 1

解决方案是将这种依赖性添加到项目中:

实现'androidx.lifecycle：生命周期扩展： 2.1.0'

不知道为什么会这样，但确实如此。
