Asynchronous shell commands with screen
You can try running the game_server.sh in the background like this without using screen at all:
./game_server.sh &or, you can try changing your build.xml like this:
<?xml version="1.0" ?><project default="restart_game_server" name="server"> <target name="restart_game_server"> <sshexec host="x.x.x.x" username="root" password="xxx" command="cd xxx; ./game_server.sh &" trust="true" /> </target></project>
