### Dependency verification

We have a [dependencies verification](https://docs.gradle.org/current/userguide/dependency_verification.html) feature enabled in the
repository for all Gradle builds. Gradle will check hashes (md5 and sha256) of used dependencies and will fail builds with
`Dependency verification failed` errors when local artifacts are absent or have different hashes listed in the
