i develope a component and create a installation file named script.php.

this are the first lines of the file:
class com_sportsmanagementInstallerScript
{

/**
 * Constructor
 *
 * @param   JAdapterInstance  $adapter  The object responsible for running this script
 */    
public function __construct(JAdapterInstance $adapter)
{
$this->release = $adapter->get( "manifest" )->version;
}

if i install the component, i got this error:
An error has occurred.
0 Argument 1 passed to com_sportsmanagementInstallerScript::__construct() must be an instance of JAdapterInstance, instance of Joomla\CMS\Installer\Adapter\ComponentAdapter given, called in /www/htdocs/w0086dfc/joomla40/libraries/src/CMS/Installer/InstallerAdapter.php on line 1006

what am i doing wrong ?
