• How exactly is your WordPress project been set up? From a Composer template? And now you want to autoload project dependencies in your plugin? Or does your plugin have a composer.json and you want to autoload dependencies there? Did googling for "wordpress autoload plugin" shed any lights on your issue? – norman.lol Commented Oct 7, 2019 at 17:25
• Are you trying to set up and use an autoloader for your plugin? Or do you mean something else? – Tom J Nowell ♦ Commented Oct 7, 2019 at 17:35
• @leymannx I want to use composer to load the plugin classes. for now I'm requiring classes using require_once, this is not the best option because the plugin will become more modular in the future. @TomJNowell Yes, the autoloader will be used only internally from the plugin – userone2 Commented Oct 7, 2019 at 17:38
• 1 An autoloader and composer are not the same thing. Composer includes an autoloader, but is mainly a PHP package manager. If you want to autoload classes that belong to the plugin, and not a separate package, then you don't need composer. – Jacob Peattie Commented Oct 7, 2019 at 23:45

Without more context from you, I can only assume and show you what I have done that works for me using PSR4 Autoloading.

Example:

Assuming that all my custom class directories and files is in ./inc folder

In your composer.json, add this

"autoload": {
    "psr-4": {
        "Inc\\": "./inc"  
    }
}

Inc is the vendor name of your application, use this for namspacing files inside your inc directory like namespace Inc/Api;

./inc is the directory(with all the class files or nested directory) you want to autoload.

Next, do this in your terminal to generate the vendor directory & autoload the files.

composer dump-autoload

Lastly, require the the autoloading by adding this to your plugin file eg. my-awesome-plugin.php

if (file_exists(dirname(__FILE__) . '/vendor/autoload.php')) {
    require_once dirname(__FILE__) . '/vendor/autoload.php';
}
