I wanted to clarify what is the recommended Java version for flink development and builds. The docs state that Java 8 support is deprecated and Java 11 is recommended for building. (https://github.com/apache/flink/blob/master/docs/content/docs/flinkDev/building.md) However this page on setting up a dev environment for flink specifies Java 8 (https://cwiki.apache.org/confluence/display/FLINK/Setting+up+a+Flink+development+environment) The wiki page was last updated in late 2021, so I assumed it just a case of documentation that hadn't been updated yet (I'd be happy to help with that). So I set up my environment with Java 11 and it successfully builds flink. However, I also see latest discussion on the dev list the last 2 days stating binary releases must be built with Java 8. Can someone please clarify?

We currently require that releases are built with Java 8. You can run Flink either as Java 8 or Java 11 (and with 1.18, also in Java 17). Java 8 is deprecated and hopefully in the next release we can move Flink to be fully on Java 11 and Java 17

Thank you! That makes it very clear.

The CI for PRs tests on Java 8, all merged are changed every night on Java 11 too. But I do all my development in Java 11

Very helpful, thank you!
