Thanks for the feedback. I have another question about building using sbt: how can one go from import statements to figuring out library dependencies?
Would be nice to write small programs w/o an IDE and be able to go from the import statements to appending the library dependency list in a .sbt file to build. For example, I would like to test algorithm in the machine learning library ( namely: https://github.com/chiwanpark/flink/blob/FLINK-1745/flink-staging/flink-ml/src/main/scala/org/apache/flink/ml/nn/KNN.scala ), and when I run `sbt package`, I get errors since I need to add more dependencies in my build.sbt file. I can try to get an IDE and have this automated, but I would like to be able to add the right dependencies quickly on the command line.
