fileName.php does not comply with psr-4 autoloading standard, Skipping.

Hello @all,

I have been trying to understand what this issue is for almost 2 days and hence need your support to understand.

I am using PHPStorm and I have been using 8.1 and updated to 8.2, with the changes now I am getting a warning saying Class CreateTestTable located in ./database/Migrations/2021_05_03_093750_create_test_table.php doesn't comply with psr-4 autoloading standard.

For Info: I am using the nwidart/laravel-modules(v9) saying that this file is in one of the modules.

here is my composer.json for psr-4 section

 "autoload": {
        "psr-4": {
            "App\": "app/",
            "Modules\": "Modules/",
            "Database\Factories\": "database/factories/",
            "Database\Seeders\": "database/seeders/",
        },
    },

and this is the composer.json in the test module in the directory project/Modules/Test making the directory to root

"autoload": {
        "psr-4": {
            "Modules\Test\": ""
        }
    }

This is an issue as I am not able to install the composer into my modules as necessary.

Can anyone help me to understand this?

The issue you're encountering is related to the PSR-4 autoloading standard, which requires that the file path and the namespace of the class match. In your case, the class CreateTestTable located in ./database/Migrations/2021_05_03_093750_create_test_table.php does not comply with the PSR-4 autoloading standard because the namespace and the file path do not align correctly.

Here are a few steps to resolve this issue:

Check the Namespace of the Class: Ensure that the namespace declared in your CreateTestTable class matches the directory structure defined in your composer.json.

Update the Namespace in the Class File: Open the 2021_05_03_093750_create_test_table.php file and ensure the namespace is correctly set. For example, if your migrations are under the Modules\Test\Database\Migrations namespace, the file should look like this:

<?php

namespace Modules\Test\Database\Migrations;

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateTestTable extends Migration
{
    // Migration methods here
}

Update the composer.json in the Test Module: Ensure that the composer.json in your test module correctly maps the namespace to the directory. It should look something like this:
```
"autoload": {
    "psr-4": {
        "Modules\Test\": "src/"
    }
}
```
Here, src/ should be the directory where your module's code resides. Adjust this path according to your actual directory structure.
Run composer dump-autoload: After making these changes, run the following command to regenerate the autoload files:
```
composer dump-autoload
```

Verify the Directory Structure: Ensure that your directory structure matches the namespace. For example, if your namespace is Modules\Test\Database\Migrations, the directory structure should be:

project/
└── Modules/
    └── Test/
        └── src/
            └── Database/
                └── Migrations/
                    └── 2021_05_03_093750_create_test_table.php

By following these steps, you should be able to resolve the PSR-4 autoloading issue. If you still encounter problems, double-check the namespace and directory structure to ensure they are correctly aligned.
