Luke Chen updated KAFKA-16924:
------------------------------
Description:
In https://github.com/apache/kafka/pull/12148 , we removed log4jAppender
dependency, and add testImplementation dependency for `slf4jlog4j` lib.
However, we need this runtime dependency in tools module to output logs.
([ref](https://stackoverflow.com/a/21787813)) Adding this dependency back.
Current output will be like this:
{code:java}
> bin/kafka-server-start.sh config/kraft/controller.properties
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further
details.{code}
