problem lose class address when update composer 1 to 2

i have problem when install or update composer. When the composer is updated and generated, the autoload file for example autoload_classmap.php changes and no class or file is found. I do not know how to solve. Thanks for the help.

composer.json file

    ]
}

}

and when update composer say: not found class App/ClearingHourTime

class file is :

    <?php

namespace App;

abstract class Enum {
    static function getKeys() {
        $class = new ReflectionClass(get_called_class());
        return array_keys($class->getConstants());
    }
}

abstract class ClearingHourTime extends Enum {
    const OPERATION = [
        UserType::USR       =>  0,
        UserType::ADM       =>  72,
        UserType::IND_LAW   =>  72,
    ];
}

Answer

I think you have an issue with ClearingHourTime.php, in that file as you are declaring two classes. I think that this practice does not meet psr4 standard, and you are loading app/ under psr4.

To solve this problem you have two options (use only one).

1. add “classmap”: [“app/ClearingHourTime”]

"autoload": {
    "files": [
        "app/Helpers.php",
    ],
    "classmap": ["app/ClearingHourTime"],
....
}

2. add “app/ClearingHourTime” to files. like

"autoload": {
    "files": [
        "app/Helpers.php",
        "app/ClearingHourTime.php"
    ],
....
}

I hope this help
