aurlien commented on pull request #6194: KAFKA-7855: [WIP] Kafka Streams Maven
Archetype quickstart fails to compile out of the box
URL: https://github.com/apache/kafka/pull/6194
In the LineSplit.java example, the untyped KStream is resolved to
`KStream<Object, Object>`. `value.split(..)` then fails to build, because
value is of type Object.
Other possible solutions would be to add the type to the builder:
`builder.<String, String>stream(...).flatmap(..).to(...)`, or
`builder.stream(..., Consumed.with(Serdes.String(), Serdes.String()))`.
This change matches the code in the
[tutorial](http://kafka.apache.org/21/documentation/streams/tutorial).
WIP: It should be tested during compile that the Java resource files
compiles. However, I haven't found any way to achieve this. Feedback
appreciated!
