How to run sbt as daemon?

oleg-andriyanov's answer did not work in my case. (process exited soon after launch)

In a such case, try Mirko Stocker's command written in play ML below for alternative. https://groups.google.com/forum/#!topic/play-framework/ZgjrPgib0-8

# screen -d -m sbt run

This should also work

sbt -Djline.terminal=jline.UnsupportedTerminal run &

Looks like sbt requested input from your terminal. If it does not really need input (which is probably the case when you run program in background), you can run it like this:

sbt run </dev/null >output-file &

See this answer for details.

EDIT

Ok, now that was a puzzle. Short answer: run sbt as follows:

setsid nohup sbt run &

Rationale:

The reason why sbt stops is arrival of SIGTTOU signal. It is delivered to background process in several cases, which include modifying terminal configuration. This is our case because according to strace -f sbt run &, sbt does a lot of black magic under the hood like this:

[pid 16600] execve("/usr/bin/sh", ["sh", "-c", "stty -g < /dev/tty"], [/* 75 vars */] <unfinished ...>

To work this around, you can run sbt in a different session to detach it from current terminal, so that it won't open /dev/tty and mess with our terminal.
