Joomla 3 -从CLI文件加载模型

我试图加载一个模型类，它的功能在CLI脚本中为Joomla 3.6。这是我目前所看到的:

jimport('joomla.application.component.model');
JLoader::import('JoomlaupdateModelDefault', './administrator/components/com_joomlaupdate/models');
$updater = JModelLegacy::getInstance('default');
var_dump($updater);
$updater->finaliseUpgrade();

var_dump总是返回false，最后的函数调用总是返回这个:

显示错误页面的错误:Application Instantiation Error: Call到成员函数finalisupgrade () on boolean

这个错误当然是因为这个类还没有被创建，而且它实际上是一个bool类型。

所以问题仍然存在，我如何拉模型到我的php CLI应用程序和使用它的功能?

好的，我已经得到的方式的一部分，现在它返回对象，但在运行finalise它返回一个错误的实例化。对象:

错误是:

显示错误页面的错误:Application Instantiation Error:应用程序实例化错误

是部分有效的代码:

jimport('joomla.application.component.model');
jimport('joomla.application.component.view');
JModelLegacy::addIncludePath('./administrator/components/com_joomlaupdate/models', 'JoomlaupdateModel');
$updater = JModelLegacy::getInstance('Default', 'JoomlaupdateModel');
var_dump($updater);
$updater->finaliseUpgrade();
