问题
I'm running SBT under chef-solo, and it hangs trying to read from the terminal. Redirecting /dev/null into it doesn't help, even if I run the jar directly with java. It only works if I orphan it, and will only terminate when the parent chef-solo terminates. It must be closing stdin, and then reopening it, thus getting the stdin of the parent. The stack trace during the hang seems to indicate that. I suspect it has something to do with one of the plugins

回答1:
Well, after much digging, this should work but doesn't
-Dsbt.log.noformat=true
So I dug into the jline website and found this disables interrogating the terminal
-Djline.terminal=jline.UnsupportedTerminal
