Nick Burkard created FLINK-20845: ------------------------------------ Summary: 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
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)
