Aljoscha Krettek reassigned FLINK-20845: ---------------------------------------- Assignee: Nick Burkard > Drop support for Scala 2.11 > --------------------------- > > Key: FLINK-20845 > URL: https://issues.apache.org/jira/browse/FLINK-20845 > Project: Flink > Issue Type: Sub-task > Components: API / Scala > Reporter: Nick Burkard > Assignee: Nick Burkard > Priority: Major > > The first step to adding support for Scala 2.13 is to drop Scala 2.11. > Community discussion can be found > [here|https://lists.apache.org/thread.html/ra817c5b54e3de48d80e5b4e0ae67941d387ee25cf9779f5ae37d0486%40%3Cdev.flink.apache.org%3E]. > * Scala 2.11 was released in November 2017 and is quite old now. Most > open-source libraries no longer build for it. > * Upgrading libraries to support 2.13 will be much easier without 2.11. Many > do not support 2.11, 2.12 and 2.13 at the same time, so this is basically > required to get 2.13 support. > Considerations: > * The Flink Scala Shell submodule still does not support Scala 2.12. It isn't > a strict dependency for dropping Scala 2.11, but would be nice to have before > making the cut. > * Stateful functions previously needed Scala 2.11, but it looks like it [now > supports 2.12|https://github.com/apache/flink-statefun/pull/149]. -- This message was sent by Atlassian Jira (v8.3.4#803005)
