PHP Fatal error:  Cannot redeclare class AppModel in C:\workspace\site\Vendor\pear-pear.cakephp.org\CakePHP\Cake\Test\Case\Model\mode

bootstrap.php

<?php
require ROOT . DS . 'Vendor/autoload.php';

// Remove and re-prepend CakePHP's autoloader as Composer thinks it is the
// most important.
// See: http://goo.gl/kKVJO7
spl_autoload_unregister(array('App', 'load'));
spl_autoload_register(array('App', 'load'), true, true);

How can I fix that?

Even when I reregisterd the Cake Autoloader like Mark, I got Autoloading conflicts when using the auth Component, because of the Models Group, User and Product are defined a second time in Cake/Test/Case/Model/models.php

I resolved the issue by using a composer hook script and deleting the mapping within composers autoload_classmap

composer.json:

....
"scripts": {
        "post-autoload-dump": [
            "./composer_fix_autoload.sh"
        ]
    },
....

composer_fix_autoload.sh:

#!/bin/bash
mv vendors/composer/autoload_classmap.php vendors/composer/autoload_classmap.php.bak
sed '/CakePHP\/Cake\/Test\/Case\/Model\/models\.php/d' vendors/composer/autoload_classmap.php.ori > vendors/composer/autoload_classmap.php

I've discovered, that it happens, when you have some association(s) in model for which you're baking views and the associated model class isn't baked yet.

Then somehow is used mapping from autoload_classmap.php:

'AppModel' => $vendorDir . '/pear-pear.cakephp.org/CakePHP/Cake/Test/test_app/Model/AppModel.php',

Unfortunately, I have too little knowledge to fix this bug.

The error message is clear: You're loading the AppModel two times somehow.

Cannot redeclare class AppModel in C:\workspace\site\Vendor\pearpear.cakephp.org\CakePHP\Cake\Test\Case\Model\models.php on line 57

Means that AppModel was loaded somewhere else already. My guess is that you have two installations of CakePHP. The path sounds like you have it installed via Pear and your text says you've used composer as well. So I guess the script is somehow loaded two times which causes the error when it tries to load it a second time for whatever reason. You'll have to figure out from where the class is loaded the first time, you can use reflections to figure that out.

$AppModel = new AppModel(/*...*/);
$Reflection = new ReflectionClass(get_class($AppModel ));
debug(dirname($Reflection->getFileName());

Further I guess the autoloader kicks in first and then, for a reason I don't know it also tries to load the core from the Pear installation.
