I would like to accomplish running the equivalent of this
sbt -jvm-debug 5005
However I don\'t seem to be able to pass in args in Windows.
Currently, I'd downloaded the last updated sbt, exactly sbt 1.3.3 but when I want to enable debug in the project, I had the same problem as you. Investigating, I could see that I haven't this file (sbt-launch-lib.bash) in my own root C:\Program Files (x86)\sbt\bin so when I see in another machine, I could notice that sbt, It was 1.2.8 and yes it had the file that I mentioned before so I uninstalled sbt 1.3.3 and I installed sbt 1.2.8 and put in my project sbt -jvm-debug 9999 and it works.
