StepBuilder Generator

IntelliJ IDEA/Android Studio plugin that adds a 'Step Builder' action to the Generate menu (Alt+Insert) which generates a Builder class which follows the Step Builder pattern. You can read about the Step Builder pattern and why it might be a little more effective than the usual Builder pattern here.

public class Server{
    final static int DEFAULT_PORT = 8080;

    private String protocol;
    private String url;
    private String ipAddress;
    private int port;
    private String description;
    private long uptime;

    private Server(Builder builder) {
        protocol = builder.protocol;
        url = builder.url;
        ipAddress = builder.ipAddress;
        port = builder.port;
        description = builder.description;
        uptime = builder.uptime;
    }

    public static IProtocol builder() {
        return new Builder();
    }


    public interface IBuild {
        Server build();
    }

    public interface IUptime {
        IBuild withUptime(long val);
    }

    public interface IDescription {
        IUptime withDescription(String val);
    }

    public interface IPort {
        IDescription withPort(int val);
    }

    public interface IIpAddress {
        IPort withIpAddress(String val);
    }

    public interface IUrl {
        IIpAddress withUrl(String val);
    }

    public interface IProtocol {
        IUrl withProtocol(String val);
    }

    public static final class Builder implements IUptime, IDescription, IPort, IIpAddress, IUrl, IProtocol, IBuild {
