Hi,

I am studying how to build a scala program from flink-examples/.

I can see there are two source folders java/ and scala/ from IntelliJ, and
for most examples, there is a copy of examples for Java and Scala.
Executing 'mvn clean package -Pbuild-jar' would rests in a jar file under
target/. I am wondering if that is a Java or Scala example that I just
compiled? In addition, is there a way to selectively choose Java o Scala
example to build with current maven settings?

Thanks in advance,
