Probleme de copie de mes fichiers assets dans le dossier media de la racine du site

[bmdiarra]

Bonjour, je developpe un composant pour joomla et j'aimerai lors de l'installation de mon composant copier les fichiers qui sont dans mon dossier "assets" a l'intérieur du dossiers "media/mon_composant" de la racine de mon site. Pour pouvoir utiliser la ligne de code suivant:

use Joomla\CMS\Factory;
// Inclure le fichier CSS dans la page
JFactory::getDocument()->addStyleSheet(JUri::root(true) . '/media/com_mgwaffiliate/css/mgwaffiliate.css');​ 

Voici la structure mon composant:

Voici le contenu de mon fichier mgwaffiliate.xml

<?xml version="1.0" encoding="utf-8"?>
<extension type="component" method="upgrade">
<!-- 'version' attribute for extension tag is no longer used -->
<name>MGW Affiliate</name>
<!-- The following elements are optional and free of formatting constraints -->
<creationDate>Octobre 2023</creationDate>
<!-- Dummy author, feel free to replace anywhere you see it-->
<author>Site</author>
<authorUrl>https://site.com</authorUrl>
<copyright>site</copyright>
<license>GPL v3</license>
<!-- The version string is recorded in the components table -->
<version>0.0.7</version>
<!-- The description is optional and defaults to the name -->
<description>
A site component!
</description>
<!-- This is the PHP namespace under which the extension's
code is organised. It should follow this format:
Vendor\Component\ComponentName
"Vendor" can be your company or your own name
The "ComponentName" section MUST match the name used
everywhere else for your component. Whatever the name of
this XML file is, the namespace must match (ignoring CamelCase).
-->
<namespace path="src/">Madgic\Component\MgwAffiliate</namespace>

<files folder="site/">
  <folder>assets</folder>
  <folder>language</folder>
  <folder>src</folder>
  <folder>tmpl</folder>
  <filename>assets/css/mgwaffiliate.css</filename>

<media destination="com_mgwaffiliate" folder="media">

<!-- The link that will appear in the Admin panel's "Components" menu -->

</administration>
<install>
<sql>
<file driver="mysql" charset="utf8">sql/install.mysql.utf8.sql</file>
</sql>
</install>
<uninstall>
<sql>
<file driver="mysql" charset="utf8">sql/uninstall.mysql.utf8.sql</file>
</sql>
</uninstall>
<update>
<schemas>
<schemapath type="mysql">sql/updates/mysql</schemapath>
</schemas>
</update>
</extension>
​

Et lors de l'installation, j'ai eu cette erreur:
JInstaller: :Install: le fichier n'existe pas [ROOT][TMP]/install_6526990a41df8/com_mgwaffiliate/assets/css/mgwaffiliate.css

Au niveau du dossier media de la racine. Mon dossier com_mgwaffiliate est crée mais le dossier css de meme que le fichier mgwaffiliate.css n'est pas copier.
Avez vous une solution a me suggerer ou une documentation qui explique bien le processus.
Merci d'avance.

Hello.

Au lieu de

<media destination="com_mgwaffiliate" folder="media">
<filename>assets/css/mgwaffiliate.css</filename>
</media>​

mets juste

<media destination="com_mgwaffiliate" folder="media">
<folder>assets</folder>
<filename>index.html</filename>
</media>​
