What version of the buildpack you are using?

Whatever is on PWS.

If you were attempting to accomplish a task, what was it you were attempting to do?

Push the generic bake app (the thing cakephp prebuilds as a starter project).

What did you expect to happen?

It runs properly.

What was the actual behavior?

It can’t find vendor/autoloader.php.

Fatal error: require(): Failed opening required '/home/vcap/app/htdocs/vendor/autoload.php' (include_path='.:') in /private/tmp/my_app_name/bin/cake.php on line 31

Furthermore, when I cf ssh in I see that /home/vcap/app/htdocs is entirely missing a vendor folder, despite bake giving me a composer.json.
