 I had the problem with Yandex SDK version 7.2.0 for Android.

What went wrong:
Execution failed for task ':unityLibrary:generateReleaseRFile'.
> Could not resolve all files for configuration ':unityLibrary:releaseCompileClasspath'.
   > Failed to transform mobileads-7.2.0.aar (com.yandex.android:mobileads:7.2.0) to match attributes {artifactType=android-symbol-with-package-name, org.gradle.category=library, org.gradle.dependency.bundling=external, org.gradle.libraryelements=aar, org.gradle.status=release, org.gradle.usage=java-api}.
