app/console cache:warmup does not generate all cache #3570
Description
It looks like app/console cache:warmup generates all cache files except for classes.php and classes.php.meta. The only way for these files to generate is at runtime. Many environments on PaaS only have write access for a limited period of time during deployment so this is not an option.
Here is the output of an error that occurred after running the warmup command and attempting to open an app in the browser.
