I've downloaded the soruce code, it's for reading only, I found that in the 
code:

if(args.length == 0) {
            usage();
            return;
        }

        int i = 0;
        while(i < args.length) {
            String arg = args[i];

            if(arg.equalsIgnoreCase("-keystore")) {
                i++;
                keystore = args[i];
            } else if(arg.equalsIgnoreCase("-storepass")) {
                i++;
                storepass = args[i];
            } else if(arg.equalsIgnoreCase("-alias")) {
                i++;
                alias = args[i];
            } else if(arg.equalsIgnoreCase("-keypass")) {
                i++;
                keypass = args[i];
            } else if(arg.equalsIgnoreCase("-h") || arg.equalsIgnoreCase("-help")) {
                usage();
                return;
            } else {
                error("Unknown argument - " + arg);
                return;
            }
            i++;
        }

        if(keystore == null) {
            error("Keystore path didn't specified");
            return;
        }

        if(alias == null) {
            error("Key alias didn't specified");
            return;
        }


--> You check alias while I didn't even type it, I mean I shouldn't type it, 
the command is asking about the keystore so why should I type alias, it should 
be null and I think you shouldn't return.

Thanks in advance !
