Org.apache.http.ProtocolException: целевой хост не указан ⇐ JAVA

[Anonymous]

Я написал простой код httprequest/response и получаю следующую ошибку. В моем пути к классам я упомянул httpclient, httpcore, common-codecs и common-logging. Я новичок в Java и понятия не имею, что здесь происходит. Пожалуйста, помогите мне.

Код:

import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.HttpResponse;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.Header;
import org.apache.http.HttpHeaders;

public class UnshorteningUrl {

public static void main(String[] args) throws Exception
{
HttpGet request=null;
HttpClient client = HttpClientBuilder.create().build();

try {
request = new HttpGet("trib.me/1lBFzSi");
HttpResponse httpResponse=client.execute(request);

Header[] headers = httpResponse.getHeaders(HttpHeaders.LOCATION);
// Preconditions.checkState(headers.length == 1);
String newUrl = headers[0].getValue();
System.out.println("new url" + newUrl);
} catch (IllegalArgumentException e) {
// TODO: handle exception
}finally {
if (request != null) {
request.releaseConnection();
}
}
}}
