public class PerforceUtil {
	private static Logger logger = Logger.getLogger(PerforceUtil.class);
	
	public static void SaveFile(InputStream inputStream, File file) {
		try {
			FileOutputStream out = new FileOutputStream(file);

			byte[] b = new byte[1024];
			int len = 0;
			while ((len = inputStream.read(b)) != -1) {
				out.write(b, 0, len);
			}
			inputStream.close();
			out.close();

		} catch (IOException e) {
			logger.error("", e);
		} 
	}

	public static void downloadFile(String filePerforcePath, String destFolder) {
		try {
			IServer server = ServerFactory.getServer(ResourceUtil.getConfig().getProperty(Constants.P4PROTOCAL), null);
			server.connect();
			try {
