How to change HTTP port that Play2 is listening on

The documentation says:

$ play start

Note: the HTTP port can be set by passing -Dhttp.port system variable

but I'm still hitting 9000 port taken error 

$ /opt/play-2.0/play start -Dhttp.port=9001

[info] Loading project definition from /my/path
[info] Set current project to marmurka (in build file:/my/path/)

(Starting server. Type Ctrl+D to exit logs, the server will remain in background)

Play server process ID is 27505
[info] play - Application started (Prod)
Oops, cannot start the server.

Also note that the server remains in the background, Ctrl+D does not kill it (though it does if you use run instead of start). So if you are wondering why the port is still in use... that's probably the reason.

First type: play

then in console type: start 9001

The same for development mode. First: play, then: run 9001

Another way use qoutes:

play "start 9001"

play "run 9001"
