### 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

 * not necessarily the case for declaration providers (e.g. the IDE declaration provider hitting the index without caching).
 *
 * However, since symbol names providers may not be able to compute name sets per their contract, we may have to fall back to the
 * [declaration provider][org.jetbrains.kotlin.analysis.providers.KotlinDeclarationProvider].
