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?
dependencies {
compile("org.apache.beam:beam-sdks-java-core:$beamVersion")
compile("org.apache.beam:beam-runners-direct-java:$beamVersion")
compile("org.apache.beam:beam-runners-google-cloud-dataflow-java:$beamVersion")
// waiting for response on mailinglist (2.30 onwards), dataflow runner fails
// {
// exclude module: 'beam-sdks-java-io-kafka'
