The given artifact contains a string literal with a package reference ‘android.support.v4.content‘

编译时遇到，The given artifact contains a string literal with a package reference ‘android.support.v4.content’ that cannot be safely rewritten.Libraries using reflection such as annotation processors need to be updated manually to add support for androidx.

原因：

android build.gradle文件中引用的某个库，版本太旧，而工程的minSDK是androidx以上。

解决

将对应的库，更新到最新版本

我的错误库版本是：

原本

annotationProcessor ‘com.jakewharton:butterknife-compiler:8.8.1’

换成

implementation ‘com.jakewharton:butterknife:10.2.1’
annotationProcessor ‘com.jakewharton:butterknife-compiler:10.2.1’
