I need to change Acorn path folder.

I have read [docs](https://docs.roots.io/acorn/2.x/directory-structure/#advanced) and found out two ways to do that:

1. Use ACORN\_BASEPATH
2. Use filters.

Default path is `/app/web/app/cache/` for storage and bootstrap.

I have tried to define `define('ACORN_BASEPATH', getenv('ACORN_BASEPATH') ?: '/app/uploads/cache');`, but it doesn’t have effect. Same for filters which I have added directly to `function.php`

```
apply_filters('acorn/paths', [
    'storage' => 'web/app/uploads/cache'
]);
```

After unsuccessfully trying, I have started to debug Bootloader.php.

In the first step, is everything okay. Bootloader gets the right path.

```
// @codeCoverageIgnoreStart
if (defined('ACORN_BASEPATH')) {
    return $this->basePath = rtrim(constant('ACORN_BASEPATH'), '/\\');
}
```

Even in the function `findPath` we have a right path in variable `$searchPaths`, but at `return collect($searchPaths)` fires `fallbackPath`.

As a result, I still have the default paths.

What I did wrong?

Does anybody have the experience of how to do that?

I found out what path should be absolute.  
I mean should be `ACORN_BASEPATH="/app/web/app/uploads/cache"`, but not ACORN\_BASEPATH=“/web/app/uploads/cache”.

In that case, acorn Bootloader doesn’t use fallback paths but fails after and still generates files at `app/cache/acorn`

**Add in composer.json these lines** :

```
"autoload": {
    "psr-4": {
        "App\\": "app/"
    }
}
```

**Add in wp-config.php** :

```
if ( ! defined( 'ACORN_BASEPATH' ) ) {
	define( 'ACORN_BASEPATH', __DIR__. '/absolute-path-to-plugin-dir );
}
```
