Fabian Hueske commented on FLINK-2537:
--------------------------------------
I am very sorry for giving (too) late feedback on this issue.
We had example JAR files for both, Java and Scala, some time ago.
We decided to drop the Scala examples because we did not see a benefit in
providing two binaries which do exactly the same thing.
It is true, that users who want to play with the Scala examples might find it
confusing that no jar files are copied to the {{examples}} folder. However, the
JAR files of the Scala example can be found at
{{flink-examples/flink-scala-examples/target}}.
> Add scala examples.jar to build-target/examples

> Project: Flink
> Issue Type: Improvement

> Currently Scala as functional programming language has been acknowledged by
> more and more developers, some starters may want to modify scala examples'
> code for further understanding flink mechanism. After changing scala
> code,they may select this method to check result:
> 1.go to "build-target/bin" start server
> 2.use web UI to upload scala examples' jar
> 3.this time they would get confusion, why changes would be not updated.
> Because build-target/examples only copy java examples, suggest adding scala
> examples also.
> The new directory would like this :
> build-target/examples/java
> build-target/examples/scala
