Answer 1

Normally, you can specify Java command line arguments when you call play using the following pattern.

play run  -Xmx256M -Xms256M

However, looking at the python code for the play run command and the play dependencies command, they invoke Java in different ways.

The play dependencies command invokes Java without passing through -X commands (for some reason, it passes through -D commands, but not -X). Therefore, there is nothing you can do, apart from editing the deps.py file in framework/pym/play/commands and hard coding the -Xmx and -Xms settings into this file.

This not a long term solution, and I would suggest you raise a ticket on Play to allow these settings to be read from command line, or from the application.conf, but for now, I see this approach as your only option.
