Fail to push a standard Symfony PHP on Bluemix Cloud Foundry -

i'm unable push standard php symfony application on buemix cloud foundry, buildpack compilation step failed due error:

[runtimeexception]
not scan classes inside "app/appkernel.php" not appear file nor folder

here 4 steps reproduce:

1. i created new project

   composer create-project symfony/framework-standard-edition:^3.0 symfony_bluemix

2. i tested locally

   php bin/console server:run

3. i added manifest.yml file root of project

   applications:

   - path: . memory: 256m instances: 1 name: myphp-app host: myphp-app disk_quota: 1024m buildpack: php_buildpack 

4. i push project bluemix running

   cf push

anyone knows needs configured make successful?

although not manage make working know these issue comes bluemix deployment when symfony code moved htdocs folder. in case appkernel has referenced

htdocs/app/appkernel.php

in composer.json
