Description

we  import spotless plugin in order to unify Kafka code style.

Spotless version

6.14- support JDK8

6.15.0+ require JDK11 

6.23.3+ support JDK 21 but build error in JDK 8 even though we apply false in plugin block.

We couldn't find a suitable way to be compatible with all versions.

So far, here's how we do it: use 6.14.0 version, compatibility JDK8 , skip JDK21.

We will upgrade spotless version to the latest when kafka drop support JDK8 and drop CI in JDK8
