Brave 5.6.1 is too old - it doesn't have the Producer.close() method that takes a Duration. It looks like it was added in 5.6.4.

Added in version 5.6.4. – Gary Russell Aug 25 '20 at 16:48
I am just stating the fact that the version you are using does not have the method that the `KafkaTemplate` calls. So, yes, you need to use a newer version; I am not familiar with brave or how the version is determined, or why you are using an incompatible version. – Gary Russell Aug 25 '20 at 18:08
