composer autoload file after classmaps are loaded

Question

I have

"autoload": {
      "psr-4": {
          "ACME": "src/",
      },
      "classmap": ["src/"],
      "files": ["mapper.php"],
      "exclude-from-classmap": ["mapper.php"]
  },

in mapper.php I'm trying to give different namespaces for some legacy stuff.

<?php
class_alias(Some_Class::class, 'Cool\NameSpaced\Class');

I think this fails to build because mapper.php is using classes in src/ and they have not been loaded by composer yet. Is there a way to do this?

Command that I run is composer install --optimize-autoloader --no-dev

I've tried you example and it works well.

It might be related to composer command you use. Try this one instead:

composer dump-autoload

This will refresh anything from autoload section.

Here is the setup file by file:

`composer.json`

{
    "autoload": {
        "classmap": ["src/"],
        "files": ["mapper.php"]
    }
}

`mapper.php`

<?php

class_alias(Some_Class::class, 'Cool\NameSpaced\Class');

`index.php`

<?php 

require __DIR__ . '/vendor/autoload.php';

var_dump(class_exists(Some_Class::class));
var_dump(class_exists('Cool\NameSpaced\Class'));

Test in CLI

$ composer dump-autoload
$ php index.php
bool(true);
bool(true);

How to find out aliasing works?

`commposer.json`

{
    "autoload": {
        "classmap": ["src/"]
    }
}

Test in CLI

$ composer dump-autoload
$ php index.php
bool(true);
bool(false);

I've checked again and I think it's caused by something else regarding my build. Thanks! – Thellimist Oct 24 '17 at 18:08
I'm using `require(__DIR__ . '/vendor/autoload.php');` in a script and this is failing to load a `require_once` inside `Some_Class`. Do you have any ideas? – Thellimist Oct 24 '17 at 18:15
Glad it helped! What do you mean by `require_once` inside `Some_Class`? Could you provide code of `Some_class`? – Tomas Votruba Oct 24 '17 at 19:56
I see. You should never require any class like ` require_once('some_other_class.php');`. That should be already handled by composer. – Tomas Votruba Oct 24 '17 at 20:09
I know but tons of legacy stuff *shrugs*. I'm not sure why when I have `files` field inside composer.json, require_once fails whereas when I remove that part it works as expected... – Thellimist Oct 24 '17 at 20:12
All classes are already loaded by section `"classmap": ["src/"],`. – Tomas Votruba Oct 24 '17 at 20:14
Classes which has a namespace are loaded. The require_once class does not have a namespace just like SomeClass doesn't – Thellimist Oct 24 '17 at 20:15
I see. I hope this helped you – Tomas Votruba Oct 24 '17 at 20:53
