To all Scala 2.12 users,Due to a mistake during the release process of Flink 1.12.3 jars intended to be built against Scala 2.12 were actually built against Scala 2.11 . This affects all jars published to maven central; the convenience binaries are not affected.
Scala 2.12 users are advised to not upgrade to Flink 1.12.3, and instead wait for 1.12.4, which we will try to release as soon as possible.
Regards, Chesnay
