AbstractResponseHandler Error

[devourer17]

Issue Summary

I am using sendgrid inside a network secured by firewall. I consume several external api from my java application. I set the proxy settings as below to connect to the external APIs. I'm using sendgrid-java:4.0.0, java-http-client:4.0.0, (Apache)HttpComponents(4.5.2), Java 1.8
Though I'm receiving the mail; I'm getting this exception:

 Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/http/impl/client/AbstractResponseHandler

My code goes like this:

                Mail mail = new Mail();
		Email fromEmail = new Email(), toEmail = new Email();
		Content content = new Content();
		Personalization personalization = new Personalization();
		fromEmail.setName(contactName);
		fromEmail.setEmail(fromEmail);
		toEmail.setEmail(toEmail);
		content.setType("text/html");
		content.setValue(contentData);
		personalization.addTo(toEmail);
		mail.setFrom(fromEmail);
		mail.setSubject(subject);
		mail.addContent(content);
		mail.setReplyTo(toEmail);
		mail.addPersonalization(personalization);

		CloseableHttpClient httpclient = HttpClients.custom().useSystemProperties().setProxy(new HttpHost(httpProxy, port)).build();
		Client client = new Client(httpclient);
		SendGrid sg = new SendGrid(apiKey, client);

		//SendGrid sg = new SendGrid(apiKey);
		
		Request requestEmail = new Request();
		try {
			requestEmail.setMethod(Method.POST);
			requestEmail.setEndpoint("mail/send");
			requestEmail.setBody(mail.build());
			
			Response response = sg.api(requestEmail);
			System.out.println("Email Status: " + response.getStatusCode());
		} catch (IOException ex) {
			System.out.println(ex.getMessage());
			ex.printStackTrace();
		}

Hello @devourer17,

It looks like you are missing this class: https://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/impl/client/AbstractResponseHandler.html

Could you please upgrade java-http-client to 4.1.0? With these dependencies.

I hope that helps!

With Best Regards,

Elmer
