After sbt run, a project I'm working on is showing some errors/warnings, and seems to pause.
How do I quit sbt from here?
If I press ctrl+z or ctrl+c, it stops, but the next time I run sbt it says:
[warn] sbt server could not start because there's another instance of sbt running on this build.
Running multiple instances is unsupported
So how do I (force?) quit correctly after sbt run?
