Google Oauth2 refresh_token is empty

Question

I do code request with string:

https://accounts.google.com/o/oauth2/v2/auth?
   scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fdrive.metadata.readonly&
   state={%22externalUserId%22:%22TEST%22}&
   access_type=offline&
   include_granted_scopes=true&
   redirect_uri=http://localhost:3344/oauth2/google/callbackcode&response_type=code&
   client_id=676016849609-r53vpjccpr9kf5uvuul7h6kvek1id2oh.apps.googleusercontent.com

I receive oauth2 code. I do token request code based with java client.

private AuthorizationCodeFlow flow;
@PostConstruct
public void init() {
    NetHttpTransport transport = null;
    try {
        transport = GoogleNetHttpTransport.newTrustedTransport();
    } catch (GeneralSecurityException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    try {
        flow = new GoogleAuthorizationCodeFlow.Builder(
                transport, JSON_FACTORY, GoogleClientSecrets.load(JSON_FACTORY,
                new InputStreamReader(GoogleCalendarClient.class.getResourceAsStream("/client_secret_676016849609-r53vpjccpr9kf5uvuul7h6kvek1id2oh.apps.googleusercontent.com.json")))
                , SCOPES).build();
    } catch (IOException e) {
        e.printStackTrace();
    }
    callBackPattern = String.format(callBackPattern, provider().lowerCaseName());
}

flow.newTokenRequest(oauthCode)
                .setRedirectUri(callBackPattern)
                .execute();

And as result i receive TokenResponse

  "access_token": "ya29.Glv_A8Fidn8cRmQveIy0pbDIjcxssKN61X20u4zjlDYV1NbiC-QO593_isRa8Q5ngSFr-y-zICjXw1WZy4OguOh90SCyPnz0NGYpw7I4fahzH7NORQm-bbnA9Chr",

  "token_type": "Bearer"
}

There is no errors, because of correct access_token. The problem is that TokenResponse doesn't contain refresh_token data.

How could I get a refresh_token?

I tried google oauth2 java examples to receive token, there is also no refresh_token — Sergii, Feb 27 '17 at 13:10

The refresh token send just in first time you authorize the app and then you need to save it some where . So you have to delete first the authorize you give to your app from here and then try again .

following doc: `refresh_token` _A token that you can use to obtain a new access token. Refresh tokens are valid until the user revokes access. Again, this field is only present in this response if you set the `access_type` parameter to `offline` in the initial request to Google's authorization server_. – Sergii Feb 27 '17 at 13:35
..trying to delete first authorize – Sergii Feb 27 '17 at 13:36
Exactly . In your request you set access_type="offline" so the request is OK. You try to revokes the access to your app and ask again for token ? You need to save this refresh token to use him to get another access token because the access token is valid just for hour. – OriEng Feb 27 '17 at 13:38
