Generating bundle with SensioGeneratorBundle gives error symfony 3.4

Question

I'm getting trouble generating a new bundle siwth sensio/generator-bundle, symfony ^3.4, what i do is:

> symfony new calendar --version=^3.4
> cd calendar
>  composer require sensio/generator-bundle

> php bin/console generate:bundle:
> planning on sharing this bundle: yes
>  Bundle namespace: Nmateo/CalBundle
> Bundle name"NmateoCalBundle": [enter]
> Target Directory"src/": [enter]
> Configuration format"xml": [enter]

> symfony new calendar --version=^3.4
> cd calendar
> composer require sensio/generator-bundle

> php bin/console generate:bundle:
> planning on sharing this bundle: yes
> Bundle namespace: Nmateo/CalBundle
> Bundle name"NmateoCalBundle": [enter]
> Target Directory"src/": [enter]
> Configuration format"xml": [enter]

Then i get this message:

The command was not able to configure everything automatically.
You'll need to make the following changes manually.
-Edit the composer.json file and register the bundle namespace in the "autoload" section:

-Edit /home/nmateo/Documents/calendar/src/Kernel.php and add the following bundle in the AppKernel::registerBundles() method:
new Nmateo\\CalBundle\\NmateoCalBundle(),

So i registered it in autoloader:

   "autoload": {
   "psr-4": {
        "App\\": "src/",
        "Nmateo\\CalBundle\\": "src/Nmateo/CalBundle/"
    }
},
"autoload-dev": {
    "psr-4": {
        "App\\Tests\\": "tests/",
        "Nmateo\\CalBundle\\": "src/Nmateo/CalBundle/"
    }
},

and added new Nmateo CalBundle NmateoCalBundle to the end of registerBundles in Kernel.php:

    public function registerBundles()
{
    $contents = require $this->getProjectDir().'/config/bundles.php';
    foreach ($contents as $class => $envs) {
        if ($envs[$this->environment] ?? $envs['all'] ?? false) {
            yield new $class();
        }
    }
    new Nmateo\CalBundle\NmateoCalBundle();
}

and do the composer dump-autoload:

Generated autoload files containing 0 classes

And then i start my server and got this error, i tried many times..:

EDIT: Sorry for the text in codes quote but the stackoverflow is giving me headaches since it dont want to publish my question it says: please place your code in code quotes buy all my code was already in codes quotes..

Answer 1

Read GitHub repository before use any bundle. This bundle can`t works well with Symfony 4.0

Symfony 3.4 is equal to LTS Symfony 4.0

Sensiolabs uses *.4th versions as feature-freeze version.

"WARNING: This bundle does not support Symfony 4. It also does not support the new bundle-less directory structure as created by Symfony Flex. Use the Maker bundle instead."

Answer 2

Symfony 3.4 has an issue with generating a new bundle its a known issue, https://github.com/symfony/symfony-standard/issues/1098 to fix that change your code as below

"autoload": {
"psr-4": {
    "": "src/"
}

What we did is that we specified in the composer that every new generated bundle will be imported from /src

To finish the procedure you'll need to run

composer dump-autoload

make sure you have the file composer.phar or download it from here https://getcomposer.org/download/

hope it helps
