Failed to resolve variable '${animal.sniffer.version}' when migrate to AndroidX

Question

I\'m using Android Studio 3.2 Beta5 to migrate my project to AndroidX. When I rebuild my app I got these errors:

ERROR: [TA

Answer 1

If you are using dagger or butterknife, please make sure to update it to the latest version. Or, if you have another injection library used in your project, you can try to check it if it support androidx or no.

I've found same error, the problem is on my dagger and butterknife. Have fixed it by updating it to newest version.
