* [gradle] Add recommendations to validate task * Use current version of Gradle Plugin in build checks. * Fix gradle project build version confusion in CI * [gradle] Bump samples to 5.2.1 wrapper Previously, the Gradle plugin was building in CI against openapi-generator 4.2.0 and Gradle version 4.10.2. At some point, a contribution was made with an API which is incomatible at 4.10.2 and due to a release script error which pinned the local-spec version to release 4.2.0, we didn't notice this inconsistency. This bumps the project to build against Gradle 5.2.1.
