Hello!
Recently, we need to build a compilation and development environment for Kafka 2.7.0 source code. Now the source code can run successfully. However, when we execute "gradle install" or "gradle build", we will report an error: @ nowarn annotation does not suppress any warnings. The details are as follows: If you delete the @ nowarn annotation according to the location of the error, you will still report other errors, so please find out if there is a good solution, and hope to get your reply. Thank you! The gradle version used is 6.6 The scala version used is 2.13.4
