Description

Note: this ticket blocks Gradle major version upgrade (7 -->> 8): KAFKA-14680

Rationale:

• build works fine in trunk with Gradle 7.6 and spotless gradle plugin 6.13.0 for all currently used JDK versions (that is: JDK 8 / JDK 11 / JDK 17)
• however, recent spotless gradle plugin versions (6.14.+) support only JDK 11+ versions: https://github.com/diffplug/spotless/blob/main/plugin-gradle/CHANGES.md#6140---2023-01-26
• at the moment Kafka build powered by Gradle 8.0 breaks when combined with all relevant spotless gradle plugin versions (from 6.13.0 to 6.15.0); github issue is created here
• given a fact that Kafka still needs to support JDK 8 builds (until Kafka version 4.0) it is reasonable to simply remove spotless checks out of Jenkinsfile (and re-introduce them when the time comes).

For even more details see GitHub discussion here: https://github.com/apache/kafka/pull/13205#issuecomment-1431575644

Note: spotless plugin configuration in build.gradle is out of this ticket scope.
