Description
General summary
If you run any command via the --exec flag which does not exit (like a server), then --file-watch does not build again if the files changes.
I can understand why that is, and it is probably how the implementation is - but it is counter-intuitive. Other dev tools (like gunicorn, go's reflex) works as expected. If a file changes, even with server like commands, it rebuilds/reloads and runs the commands again.
Steps to reproduce
stack build --fast --exec "sleep infinity" --file-watch
- Change a file in the same project
Expected
The build happens again, and the exec command is run again.
Actual
Nothing happens. (Because the exec command never exited)
