Hi Nico; I found the problem. I am also using xgboost. Its library has old version of flink. I removed xgboost's jar with depencies library . Thank you for your interest.

I failed to reproduce your error. How did you set up your project: SBT, Maven? Maybe its dependency management is referring to an old version of flink? Maybe different versions of scala are mixed? In that case, you may try setting up a new project: https://ci.apache.org/projects/flink/flink-docs-release-1.2/quickstart/ scala_api_quickstart.html When do you get the error? During compilation in eclipse? After submitting the job to flink?
