problems when developing google-oauth2 extension

franklingu

hi everyone, I am trying to create google-oauth2 flarum extension. I am still pretty new to PHP and composer and stuff. Currently I am facing this error: FastCGI sent in stderr: "PHP Fatal error: Uncaught exception 'ReflectionException' with message 'Class Flarum\Auth\Google\Listener\AddClientAssets does not exist' in /var/www/flarum/vendor/illuminate/container/Container.php:741
the whole stacktrace:

2016/03/16 14:58:16 [error] 4079#0: *1 FastCGI sent in stderr: "PHP Fatal error:  Uncaught exception 'ReflectionException' with message 'Class Flarum\Auth\Google\Listener\AddClientAssets does not exist' in /var/www/flarum/vendor/illuminate/container/Container.php:741

#5 /var/www/flarum/extensions/flarum-auth-google/bootstrap.php(16): Illuminate\Events\Dispatcher->subscribe('Flarum\\Auth\\Goo...')

I have modified my composer / auload_psr4.php (not sure if it is needed, but I found something like this one line)

'Flarum\\Auth\\GitHub\\' => array($baseDir . '/extensions/flarum-auth-github/src'),
    'Flarum\\Auth\\Facebook\\' => array($baseDir . '/extensions/flarum-auth-facebook/src'),
    'Flarum\\Auth\\Google\\' => array($baseDir . '/extensions/flarum-auth-google/src'),

so does not that mean I have make flarum-auth-google/src discoverable by loaders?

franklingu You should never touch the files in the vendor/ directory. These are either dependencies that Composer installs for you, or autoloaders generated automatically for you.

To get autoloading working, you need to configure your autoloading rules in your package's composer.json file. Please read the relevant documentation, it's really worth it! Once that's done, you can run composer dump-autoload - that will generate the proper autoloaders for the rules you configured.

P.S.: Also good:

franklingu It might be a good idea to run through the Quick Start tutorial once ... it explains some of the basics you need to know about, like choosing a different vendor name for your project.

Just thought I'd mention that in case no one else had yet.

As answered on gitter:

Your composer.json autoload setting has to point to the right namespace.
You will need to use your own vendor (Flarum in Flarum\Auth\Google), because you're not Flarum. I suggest you use FrankLingu\Auth\Google.
You might need to either use Franz Liedke's studio or use composer repository path: https://discuss.flarum.org/d/1608-extension-development-using-composer-repositories-path

Dominion thanks for the tip. I only glanced at it and I guess I will read it more carefully this time
