resource android:attr/fontVariationSettings and error: resource android:attr/ttcIndex not found

Question

I got an error as below recently on the Instant App compilation

[2018-09-24T04:42:32Z] FAILURE: Build failed with an exception. [2018-09-24T04:42:32Z] [2018-09-24T04:42:32Z] * What went wrong: [2018-09-24T04:42:32Z] Execution failed for task ':base-feature:processProductionReleaseFeatureResources'. [2018-09-24T04:42:32Z] > Android resource linking failed [2018-09-24T04:42:32Z] Output: /project/base-feature/build/intermediates/incremental/mergeProductionReleaseFeatureResources/merged.dir/values/values.xml:630: error: resource android:attr/fontVariationSettings not found.

[2018-09-24T04:42:32Z] error: failed linking references.

It was all the while compile good, and nothing change. Then suddenly the compile now fail with this. What could cause this issue, and how to resolve?

Apparently the issue is due to butterknife 9.0.0-SNAPSHOT

dependencies {
    implementation 'com.jakewharton:butterknife:9.0.0-SNAPSHOT'
    annotationProcessor 'com.jakewharton:butterknife-compiler:9.0.0-SNAPSHOT'
}

I have filed as issue in https://github.com/JakeWharton/butterknife/issues/1371
