CredentialsProvider provider = new BasicCredentialsProvider();UsernamePasswordCredentials credentials = new UsernamePasswordCredentials("username", "user1Pass");provider.setCredentials(AuthScope.ANY, credentials);HttpClient client = HttpClientBuilder.create() .setDefaultCredentialsProvider(provider) .build();
