Using mvnsh processes standard in file descriptor to send commands

[abargnesi]

I would like to control mvnsh by sending commands to the process from scripts. For example if I have the mvnsh process id of 18450 then I would send a command to standard in like:

printf "mvn package\n" > /proc/18450/fd/0

However this only echoes "mvn package" to the mvnsh terminal followed by a line feed. This makes sense because standard in points to the terminal for the mvnsh process.

Can mvnsh be configured to read commands from a named pipe instead? This way one could script commands to the mvnsh process and still be able to eliminate JVM boot time.

I suppose its technically possible, though wasn't really designed to do that :-\

Unless use of FD was a requirement, would be much easier (and portable) to implement with a simple tcp-socket server.
