I'd be +1 to making it optional as well. Looks really like an overhead
for users not using avro.

It worked before 2.30. It's fine for when you're using Confluent
Kafka, but feels like a hard dependency for non-Kafka users. Certainly
the requirement for including an extra repo. Certain companies have to
go through a lengthy process to include extra repo's. Feels like a
strange requirement, for.... nothing. Isn't it a bug in the
DataflowRunner?

Hi Alex,
Yes, starting from Beam 2.20.0, "beam-sdks-java-io-kafka”
requires an additional dependency “kafka-avro-serializer” from
external repository (https://packages.confluent.io/maven/
<https://packages.confluent.io/maven/>).
This is reflected in published POM file:
https://search.maven.org/artifact/org.apache.beam/beam-sdks-java-io-kafka/2.31.0/jar
<https://search.maven.org/artifact/org.apache.beam/beam-sdks-java-io-kafka/2.31.0/jar>
Did it work for you before version 2.30.0?
Could you share your build.gradle file?

Hi all,
I've been building for years via gradle. The dependency
management is probably a bit different from that of maven, but it
seems that dataflow now requires Confluent Kafka dependencies.
They are not available in Maven Central. This feels wrong for an
Apache project.

Excluding the dependencies "exclude module:
'*beam-sdks-java-io-kafka*'" doesn't work with:
Exception in thread "main" java.lang.NoClassDefFoundError:

This happens from version 2.30 onwards. Is this intended?!
