Errors trying to compile

[andreabono]

I'm trying to compile the source code on my Mac with gradle 6.9.1 and also gradle 7.
I get many errors like

FAILURE: Build failed with an exception.

* Where:
Settings file '/Users/andreabono/Desktop/kafka-message-tool/settings.gradle'

* What went wrong:
Could not compile settings file '/Users/andreabono/Desktop/kafka-message-tool/settings.gradle'.
> startup failed:
  General error during semantic analysis: Unsupported class file major version 61

Is there a specific version of gradle to be used?
