So I read like 100 post about this before deciding on creating this issue.

This problem is actually very specific and it's 100% reproducable.

I created a git branch lets call it storeUpdate, and in this branch I created a file called

app/Http/Controllers/Admin/BatchUpdateStoresController.php

which has the following:

namespace App\Http\Controllers\Admin;

use App\Http\Requests;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Repositories\BatchUpdateStores;

class BatchUpdateStoresController extends Controller

and I've added it to the routes.php file:

app/Http/routes.php|214| $api->put('stores', 'Admin\BatchUpdateStoresController@update');
app/Http/routes.php|215| $api->post('stores', 'Admin\BatchUpdateStoresController@upload');

also the relevant part in my composer file:

"autoload": {
    "classmap": [
        "database"
    ],
    "psr-4": {
        "App\\": "app/"
    }
},
"autoload-dev": {
    "classmap": [
        "tests/TestCase.php",
        "tests/Helpers/",
        "tests/Traits/"
    ]
},

However, when I switch the branch to another git branch, and I try to run php artisan, I get this error:

[ReflectionException] Class App\Http\Controllers\Admin\BatchUpdateStoresController does not exist

I find the above error interesting, as indeed that file doesn't exist (notice the actual file is app/Http/Controllers/Admin/BatchUpdateStoresController.php, so app != App, but aren't I already taking care of this in the psr-4 section of my composer.json file?

Ideas?

what i tried

all the usual stuff including:

• composer dump-autoload
• composer update
• composer update --no-scripts
• php artisan cache:clear
• php artisan api:clear
• php artisan route:clear

h2. udpdate

based on Edwards answer the following worked:

1. if you go to the git branch that doesn't have that class.. by definition, any php artisan will blow up, so then you already don't have access to some php artisan commands such as php artisan route:clear
2. therefore, go back to the original branch that has the above class and make sure php artisan runs
3. run php artisan route:clear
4. switch branches
5. profit

Try php artisan route:clear if don't solve, put your complete exception.

how to do it without php artisan

since php artisan is already jammed, you should simply delete bootstrap/cache/routes.php (ie in case you don't want to switch branches)

note: after you switch branches, you'll have to run
php artisan api:cache or else it will complain that there are no routes
