The definition for "kreait\firebase\factory" has no class.

The problem

Installed the bundle (version 1.2) using composer. Added the bundle to the AppKernel.php and pushed the commit to GitHub. My build is failing due to the following error:

[Symfony\Component\DependencyInjection\Exception\RuntimeException]                                                                                                         
  The definition for "kreait\firebase\factory" has no class. If you intend to inject this service dynamically at runtime, please mark it as synthetic=true. If this is an a  
  bstract definition solely used by child definitions, please add abstract=true, otherwise specify a class to get rid of this error. 

Environment

• PHP Version:
  7.1.33
• Symfony version:
  2.8.52
• Firebase PHP SDK and Bundle version:
  kreait/firebase-bundle 1.2.0 Symfony Bundle for the Firebase Admin SDK
  kreait/firebase-php 4.18.0 Firebase Admin SDK
  kreait/firebase-tokens 1.7.2 A library to work with Firebase tokens
  kreait/gcp-metadata 1.0.1 Get the metadata from a Google Cloud Platform environment.

Details

Tried to set up the bundle with the project, by registering it in AppKernel.php, which is one of the initial steps and it is failing at that point.

Code to reproduce issue

Inside app/AppKernel.php

// ...
class AppKernel extends Kernel
{
    // ...

    public function registerBundles()
    {
        $bundles = array(
            // ...
           new Kreait\Firebase\Symfony\Bundle\FirebaseBundle()
        );
        // ...
    }
}

I believe you need to write new \Kreait instead of new Kreait (prepend a backslash)

I tried this out but the issue remains

1.2 is a rather old release of the bundle, it might be a bug. Is there a reason why newer 1.x versions of the bundle don't work?

My project uses symfony version 2.8, kreait/firebase-php version 4.18 and firebase-bundle 1.2 seems like the last version compatible with the symfony and firebase-php version used by the project

Have you added code to your application using the SDK, or does the error occur already only by adding the bundle?

Unfortunately I don't have the capacities at the moment to look into it (and Symfony 2.x has been out of support for quite some time now), that's why I currently only can ask question to help guessing what the issue might be.

Given that it's broken for you, it's totally possible that the bundle is generally broken for Symfony 2.x. Perhaps the best solution would be to take the bundle as a kind of blueprint and implement it yourself specifically for your project 🤔

Tried to update my firebase-php version to a higher version that supports Symfony 2.8 so that I could update the firebase-bundle version. I directly tried to update the firebase-php to version 4.35 to be able to use version the bundle version 1.7, however the installation itself failed. I tried to update the firebase-php version to 4.22 so that I could upgrade to bundle version 1.3, but this issue remains in that version.

@jeromegamez I am unable to create a PR on the older tag of the repository (1.2.0)

[jeromegamez]

I just released 1.2.1 with your changes. Happy coding!
