Consumir API com Digest Auth

Programação Java
#1

Dae galera, trabalho com ColdFusion e recentemente preciso fazer uma integração com uma API. Contudo, preciso que ela seja em Java, de acordo com as necessidades do nosso sistema.

Tenho a seguinte URI
curl -k --digest -u usuario:senha https://api.uni5.net/cliente

Vi alguns tópicos muito bons mas mesmo assim não consegui chegar ao resultado final porque um exemplo usa Post, e outro que usa GET parece não encontrar a URL passando a porta no final da URL

			HttpGet httpget = new HttpGet(&quot;/&quot;);

			System.out.println(&quot;Executing request &quot; + httpget.getRequestLine() + &quot; to target &quot; + target);
			
			for (int i = 0; i &lt; 3; i++) {
				
				CloseableHttpResponse response = httpclient.execute(target,	httpget, localContext);
				try {
					System.out.println(&quot;----------------------------------------&quot;);
					System.out.println(response.getStatusLine());
					EntityUtils.consume(response.getEntity());
				} finally {
					response.close();
				}
			}
		} finally {
			httpclient.close();
		}
	}

}

Alguém sabe uma maneira simples de fazer, sem utilizar muita dependência.
Estou usando hoje somente httpclient e dependências.

&lt;dependency&gt;
	&lt;groupId&gt;org.apache.httpcomponents&lt;/groupId&gt;
	&lt;artifactId&gt;httpclient&lt;/artifactId&gt;
	&lt;version&gt;4.3.1&lt;/version&gt;	
&lt;/dependency&gt;

Obrigado!
