Sources jars are missing in Maven repository

[NersesAM]

Sources jar are missing from maven repo which makes it hard to debug or quick look at the source code inside the IDE where sources for given version can be downloaded with one click. Whereas now one has to go and clone the github repo and attach sources manually.

example:
http://packages.confluent.io/maven/io/confluent/kafka-avro-serializer/5.2.1/kafka-avro-serializer-5.2.1.jar <- works great
http://packages.confluent.io/maven/io/confluent/kafka-avro-serializer/5.2.1/kafka-avro-serializer-5.2.1-sources.jar <- doesn't 😞
