Error message: CAPTCHA is required

[GoogleCodeExporter]

When running crawler.jar, an error response says "A CAPTCHA is required. (A 
response with this error code will also contain an image URL and a CAPTCHA 
token.)

What steps will reproduce the problem?
1. build using ant
2. run java -jar crawler.jar birds

This was done using Ubuntu 10.10, Ruby 1.9. Also tested on another ubuntu based 
box.

This error occurs when one logs in using the google credentials multiple times 
in a short span of time. i.e. run the crawler, stop it, make a little change, 
and run it again, and stop, and make some change. Your credentials will start 
working automatically after 10 ~ 15 minutes or so. As for the re-captcha, You 
cannot see it because the API this crawler makes use of does not have this 
feature implemented.

Any idea what might cause this problem if I have never run the crawler before? 
I get this CAPTCHA error as well. Might have something to do with the 
credentials I put into secure.java? Hmmm. 

Mind telling me exactly what needs to be put in these fields?

        public Secure() {
                preferences.put("username_key", "username@gmail.com");
                // preferences.put("more username", "username1@gmail.com");
                // preferences.put("more username 2", "username2@gmail.com");
                preferences.put("password_key", "password");
        }

        public String getUsername() {
                return preferences.get("username_key", null);
        }

        public String getPassword() {
                return preferences.get("password_key", null);

public User[] getUsers() {
                /*
                 * Ideally, one would want 11+ username. 1 username per Android version,
                 * and the other username for crawling images and comments. For Testing
                 * purposes, one can add the same username to different index array.
                 */
                User[] users = new User[17];
                users[0] = new User(getUsername(), getPassword());
                users[1] = new User(getUsername(), getPassword());
                users[2] = new User(getUsername(), getPassword());
                users[3] = new User(getUsername(), getPassword());
                users[4] = new User(getUsername(), getPassword());
                users[5] = new User(getUsername(), getPassword());
                users[6] = new User(getUsername(), getPassword());
                users[7] = new User(getUsername(), getPassword());
                users[8] = new User(getUsername(), getPassword());
                users[9] = new User(getUsername(), getPassword());
                users[10] = new User(getUsername(), getPassword());
                users[11] = new User(getUsername(), getPassword());
                users[12] = new User(getUsername(), getPassword());
                users[13] = new User(getUsername(), getPassword());
                users[14] = new User(getUsername(), getPassword());
                users[15] = new User(getUsername(), getPassword());
                users[16] = new User(getUsername(), getPassword());

                return users;
        }

Sounds straightforward enough, but you never can be too sure...

Does the Google Account you input into secure.java need to be associated with 
an Android phone?
