Я использую компоненты HttpClient из Apache для следующей простой программы и вижу следующее исключение:

Exception in thread "main" java.lang.NoSuchFieldError: INSTANCE

public class HttpExample {

    public static void main(String[] args) {
        HttpClient client = HttpClientBuilder.create().build();
        HttpGet request = new HttpGet("https://www.google.com/?q=java");

        try {
            HttpResponse response = client.execute(request);
            System.out.println(response.getStatusLine());

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Я использую

HTTPClient-4.3.3.jarHttpcore-4.3.2.jar

Есть идеи?
