/**
 * for twitter4j-4.0.5, "tweet_mode=extended" workaround<br>
 * <br>
 * You can add this class to your project and run java:
 * <pre>-Dtwitter4j.http.httpClient=twitter4j.WorkaroundLongTweetHttpClientImpl</pre>
 * or rename this to "twitter4j.AlternativeHttpClientImpl" if no twitter4j-http2-module.<br>
 * <br>
 * This is only one way to rewrite GET parameter in twitter4j without modify.<br>
 * If you need get "display_text_range" property, use {@link ConfigurationBuilder#setJSONStoreEnabled(boolean)} and {@link TwitterObjectFactory#getRawJSON(Object)}
 *
 * @see twitter4j.HttpClientFactory

easy workaround.

• Add tweet_mode=extended parameter to GET request
• Rename full_text to text in all JSON response

Thanks for posting this, works beautifully.

You can just add setTweetModeExtended(true) to your twitter4j ConfigurationBuilder as is explained perfectly in this blog post. Best and easiest to implement solution that I've found.

twitter4j.conf.ConfigurationBuilder()
      .setOAuthConsumerKey(""))
      .setOAuthConsumerSecret("")
      .setOAuthAccessToken("")
      .setOAuthAccessTokenSecret("")
      .setTweetModeExtended(true)
