Error in attempting to create a bundle within symfony2 - php

Question

I have installed symfony2 and i have ensured the application has been installed correctly and i am trying to create a bundle for my project and i seem to be getting this message and i have edited the composer.json manually and added the correct bundle to the file:
Generating the bundle code: OK
Checking that the bundle is autoloaded: FAILED
Confirm automatic update of your Kernel [yes]? yes
Enabling the bundle inside the Kernel: OK
Confirm automatic update of the Routing [yes]? yes
Importing the bundle routing resource: OK
i have ensured composer has been configured correctly and i have removed previous namespaces from appkernel.php and routing.yml any help would be much appreciated.
this is my composer.json file:

I also encountered the same problem while generating my first bundle. I did the following things:
1. Make sure you have Composer installed before generating a bundle.
2. If the same failure message occurs on generating bundles, then in the terminal type this in your project directory $ sudo composer dumpautoload -o.
This will run your application.
