Question about generate-sdk

[mattaltepeter]

I've been using this as a tutorial of sorts while I mess with swagger-codegen for the first time. When I run the generate-sdk shell script for php, I don't appear to get a generated ApiClient.php file that is then shown in the connect-php-sdk example:

require 'vendor/autoload.php';

$access_token = 'YOUR_ACCESS_TOKEN';
# setup authorization
$api_config = new \SquareConnect\Configuration();
$api_config->setHost("https://connect.squareup.com");
$api_config->setAccessToken($access_token);
$api_client = new \SquareConnect\ApiClient($api_config);
# create an instance of the Location API
$locations_api = new \SquareConnect\Api\LocationsApi($api_client);

Is that file supposed to be generated by swagger-codegen? If so, what might I be doing wrong?
