You are correct, that is a typo. Very well done for spotting it, will
fix it right away.
We can conclude that the current SNAPSHOT version does not build with
scala 2.12 at the moment; hopefully there aren't too many issues.

In the meantime, I had a look at the Travis YAML file for examples how
there the compilation for 2.12 is happening. It appears that 1) there
might be a typo, because the build profile is 2.112 instead of 2.12
(see https://github.com/apache/flink/blob/master/.travis.yml#L143) and
there’s also not a build profile for only 2.12, it always includes Hadoop
Thanks, Martijn

Hi all,
I’m trying to build Flink (from current master branch) for Scala 2.12,
using:
mvn clean install -Pscala-2.12 -Dscala-2.12 -DskipTests
It fails for me on the with this error:
[ERROR]

Anyone an idea how to fix this?
Best regards,
