• What went wrong:
  Execution failed for task ':app:processDebugManifest'.

  Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
  is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
  Suggestion: add 'tools:replace="android:appComponentFactory"' to element at AndroidManifest.xml:5:5-21:19 to override.

As mentioned in the change log, 10.0.0 only supports AndroidX-enabled projects. If you have not yet migrated to AndroidX you need to use 9.0.0 for now.

It was solved by migrating to AndroidX, and configuring the dependency
implementation 'com.jakewharton: butterknife: 8.8.0'
annotationProcessor 'com.jakewharton: butterknife-compiler: 8.8.0'
