After restarting sbt on file changes - equivalent to `~ compile` for` run`

I know it is possible to recompile or rerun tests for file changes. I want to know if it is possible to accomplish something like this for a command run

. ~ run

does not work. (This makes sense since the run never ends.)

Is there a way to create a task that monitors file changes, exit the running server, and restart it?

If not for some other tool, would you suggest getting the same behavior?
