    "http", "proxy.example", 8080);
var credentials = new org.apache.hc.client5.http.impl.auth
    .BasicCredentialsProvider();
credentials.setCredentials(
    new org.apache.hc.client5.http.auth.AuthScope(proxy),
    new org.apache.hc.client5.http.auth.UsernamePasswordCredentials(
        proxyUser, proxyPassword.toCharArray()));

var http = org.apache.hc.client5.http.impl.classic.HttpClients.custom()
    .setProxy(proxy)
    .setDefaultCredentialsProvider(credentials)
