Answering to our other mail: I think getting from import statements to dependencies is not straightworward easy.
Usually if you add flink-core and flink-java or flink-scala, plus maybe flink-streaming-core you have what you need to program (transitive libraries will be resolved by Maven / sbt) and if you need to execute the program, add "flink-clients"...
