thx @matyix I had taken logs but don't have them anymore... but I can
confirm that in both cases (deps via %spark.dep or via the ui) the command
generated by the interpreter.sh is the same and does not contain the `--jar`
option. If you have a cluster at hand, you should easily be able to confirm
that it does not work via the ui. ---
