<artifactId>JRcon</artifactId>
<version>2.0</version>
</dependency>Firstly, we need the following settings:
InetSocketAddress serverAddress = new InetSocketAddress( "localhost", 25565 );
String password = "example";
String command = "broadcast Hello from Rcon!";
EventLoopGroup eventLoops = JRcon.newEventloops( numberOfThreads );Finally, we can create a new bootstrap from settings below:
Bootstrap bootstrap = JRcon.newBootstrap( serverAddress, eventLoops );
bootstrap.connect().addListener( ( ChannelFutureListener ) future -> {
if ( future.isSuccess() ) {
//Connection is sucessfully, then create a new session
JRconSession session = JRcon.newSession( future );
session.authenticate( password ).get(); //Sync authentication
System.out.println( "Authenticated: " + session.isAuthenticated() );
session.executeCommand( command ).thenAccept( System.out::println ); //Executing commands
} else {
//Handle I/O transport errors.
}
} );
