php - Symfony 2.3 Adding Google API -

i used before symfony2 , google api integration

i had question this, when use classmap in compser.json able google_client class, unable use other classes.

for example want use goole_youtubeservice. have...

$client = new \google_client(); $youtube = new \google_youtubeservice($client); 

when code recognizes google_client(), cannot find google_youtubeservice().

am missing work?

this composer.json
