Description

https://github.com/apache/kafka/commit/6e998cffdd33e343945877ccee1fec8337c7d57d added junit-platform.properties files to the test-classified kafka-clients and kafka-server-common artifacts. When a consumer is using these artifacts for its own Kafka-related tests, a warning is logged when the tests are launched:

Jul 11, 2024 10:26:21 AM org.junit.platform.launcher.core.LauncherConfigurationParameters loadClasspathResource
WARNING: Discovered 2 'junit-platform.properties' configuration files in the classpath; only the first will be used.

The fact that only the first will be used is potentially problematic. Depending on the ordering of the classpath, it may result in a consumer's own properties being ignored and Kafka's being used instead.

Can the junit-platform.properties files be removed from the published artifacts? As far as I can tell, they were only intended to affect Kafka's own tests.
