I know that this question was asked so many times, but none of answers helped me.

I&#39;m getting exception in Laravel 5

    BindingResolutionException in Container.php line 785:
    Target [App\Contracts\CustomModelInterface] is not instantiable.

What I&#39;ve done without success:

 - Register `App\Providers\AppRepositoryProvider` in `app.php` providers
 - `php artisan clear-compiled`
 - Everything works if I replace interfaces on repositories in MyService, but I feel that it&#39;s wrong (should it be handled by IoC container?).

Structure:

    app
      - Contracts
        - CustomModelInterface.php
      - Models
        - CustomModel.php
      - Repositories
        - CustomModelRepository.php
      - Providers
        - AppRepositoryProvider.php
      - Services
        - MyService.php

App\Contracts\CustomModelInterface.php

    &lt;?php namespace App\Contracts;
    
    interface CustomModelInterface {
    	public function get();
    }

App\Repositories\CustomModelRepository.php

    &lt;?php namespace App\Repositories;
    
    use App\Contracts\CustomModelInterface;
    use App\Models\CustomModel;
    
    class CustomModelRepository implements CustomModelInterface {
    	
    	private $Model;
    	
    	public function __construct(CustomModel $model) {
    		$this-&gt;Model = $model;
    	}
    
    	public function get() {
    		return &#39;result&#39;;
    	}
    }

App\Services\MyService.php (Keep business logic / layer between controller and repositories)

    &lt;?php namespace App\Services;
    
    use App\Contracts\CustomModelInterface;
    
    class MyService {
    
    	private $Model;
    	
    	public function __construct(CustomModelInterface $customModel) {
    		$this-&gt;Model= $customModel;
    	}
    
    	public function getAll() {
    		return $this-&gt;Model-&gt;get();
    	}
    }

App\Providers\AppRepositoryProvider.php

    &lt;?php namespace App\Providers;
    
    use Illuminate\Support\ServiceProvider;
    
    class AppRepositoryProvider extends ServiceProvider {
    
    	public function boot() {}
    
    	public function register() {
    		$models = array(
    			&#39;CustomModel&#39;
    		);
    		
    		foreach ($models as $idx =&gt; $model) {
    			$this-&gt;app-&gt;bind(&quot;App\Contracts\{$model}Interface&quot;, &quot;App\Repositories\{$model}Repository&quot;);
    		}
    	}
    }

My controller looks like:

    &lt;?php namespace App\Http\Controllers;
    
    use App\Services\MyService;
    
    class SuperController extends Controller {
    	
    	private $My;
    
    	public function __construct(MyService $myService) {
    		$this-&gt;My = $myService;
    	}
    
    	public function getDetails() {
    		return $this-&gt;My-&gt;getAll();
    	}
    }

composer.json

    &quot;autoload&quot;: {
    		&quot;classmap&quot;: [
    			&quot;database&quot;
    		],
    		&quot;psr-4&quot;: {
    			&quot;App\\&quot;: &quot;app/&quot;,
    			&quot;App\\Models\\&quot;: &quot;app/Models/&quot;,
                &quot;App\\Contracts\\&quot;: &quot;app/Contracts/&quot;,
                &quot;App\\Repositories\\&quot;: &quot;app/Repositories/&quot;
    		}
    	},
