You guys make it so complicated. If you read the documentation of apache httpclient, it would be super easy.

protected static void downloadDigest(URL url, FileOutputStream fos)
    throws IOException {
    HttpHost targetHost = new HttpHost(url.getHost(), url.getPort(), url.getProtocol());
    CloseableHttpClient httpClient = HttpClients.createDefault();
    HttpClientContext context = HttpClientContext.create();

    String credential = url.getUserInfo();
    if (credential != null) {
        String user = credential.split(":")[0];
        String password = credential.split(":")[1];

        CredentialsProvider credsProvider = new BasicCredentialsProvider();
        credsProvider.setCredentials(AuthScope.ANY,
            new UsernamePasswordCredentials(user, password));
        AuthCache authCache = new BasicAuthCache();
        DigestScheme digestScheme = new DigestScheme();
        authCache.put(targetHost, digestScheme);

        context.setCredentialsProvider(credsProvider);
        context.setAuthCache(authCache);
    }

    HttpGet httpget = new HttpGet(url.getPath());

    CloseableHttpResponse response = httpClient.execute(targetHost, httpget, context);

    try {
        ReadableByteChannel rbc = Channels.newChannel(response.getEntity().getContent());
        fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
    } finally {
        response.close();
    }
}
