Usage

Crossport has both a server program and a client program in a single jar package.

Launch server

java -jar crossport-0.0.1.jar --serverMode --listenPort=5566

With --serverMode, crossport will run in server mode without GUI.

With --listenPort=5566 (optional), crossport will listen to port 5566; The default value is 5566.

Launch client

Crossport will run in client mode without the argument --serverMode:

java -jar crossport-0.0.1.jar --serverAddress=127.0.0.1:5566

--serverAddress=127.0.0.1:5566 (optional) sets server address; Crossport will connect to 127.0.0.1:5566.

Build project

The project is built with gradle:

./gradlew build

The jar package will be generated in /build/libs.
