    public static void main(String[] args) {

        System.out.println("Hello Ignite");
        
        // create a new instance of TCP Discovery SPI
        
        TcpDiscoverySpi spi = new TcpDiscoverySpi();
        
        // create a new instance of tcp discovery multicast ip finder 
        TcpDiscoveryMulticastIpFinder tcMp = new TcpDiscoveryMulticastIpFinder();

需要在java后面用-cp参数把相应的jar包引入才行
如：

java -cp lib\*.jar -jar target\my-app-1.0.jar
