Subject Re: [DISCUSS] Offer Flink with Scala 2.11
Date Tue, 10 Mar 2015 10:28:39 GMT
Hey Alex,

I don't know the exact status of the Scala 2.11 integration. But I wanted
to point you to https://github.com/apache/flink/pull/454, which is changing
a huge portion of our maven build infrastructure.
If you haven't started yet, it might make sense to base your integration
onto that pull request.

Otherwise, let me know if you have troubles rebasing your changes.
