The reason is that flink-scala-shell uses scala-2.11 which uses jvm-1.6 as its target by default, that's why it can not use any library that depends on jvm-1.8.
You can use Zeppelin instead which supports scala-shell of scala-2.12, I have verified that it works in Zeppelin when you use scala-2.12. Check these links for more details. https://zeppelin.apache.org/docs/0.10.0/interpreter/flink.html https://medium.com/analytics-vidhya/learn-flink-sql-the-easy-way-d9d48a95ae57 Jing Lu <ajin...@gmail.com> 于2021年10月30日周六 上午2:03写道： > Hi Flink users, > > I am working on testing my code in start-scala-shell.sh.
