I get the __construct() argument error while trying to override 2 custom modules from same core class as:

In etc/di - Module1

<preference for="Magento\CatalogSearch\Controller\Result\Index" type="Vendor\Module1\Controller\Result\Index" />

in Controller class

class Index extends \Magento\CatalogSearch\Controller\Result\Index
{
    public function __construct(
        Context $context,
        Session $catalogSession,
        StoreManagerInterface $storeManager,
        \Magento\Framework\View\Result\PageFactory $resultPageFactory,
        Resolver $layerResolver,
        QueryFactory $queryFactory
    ) {
        parent::__construct($context,$catalogSession,$storeManager,$resultPageFactory,$queryFactory,$layerResolver);
        $this->resultPageFactory = $resultPageFactory;
        $this->layerResolver = $layerResolver;
        $this->_queryFactory = $queryFactory;
        $this->_storeManager = $storeManager;
    }

in etc/di--module2

<preference for="Vendor\Module1\Controller\Result\Index" type="Vendor\Module2\Controller\Result\Index" />

in controller module2

class Index extends \Vendor\Module1\Controller\Result\Index
{
    public function __construct(
        Context $context,
        Session $catalogSession,
        StoreManagerInterface $storeManager,
        Http $request,
        LayoutInterface $layout,
        ScopeConfigInterface $scopeConfig,
        Resolver $layerResolver,
        \Magento\Catalog\Model\CategoryFactory $catalogCategoryFactory,
        \Magento\Framework\Registry $registry,
        \Vendor\Module1\Model\Client\Connector $tglssearchClientConnector,
        QueryFactory $queryFactory,
        \Magento\Framework\View\Result\PageFactory $resultPageFactory
    ) {
        parent::__construct($context,$catalogSession,$storeManager,$queryFactory,$layerResolver);
        $this->_storeManager = $storeManager;
        $this->catalogSession = $catalogSession;
        $this->storeManager = $storeManager;
        $this->request = $request;
        $this->layout = $layout;
        $this->scopeConfig = $scopeConfig;
        $this->catalogCategoryFactory = $catalogCategoryFactory;
        $this->registry = $registry;
        $this->tglssearchClientConnector = $tglssearchClientConnector;
        $this->layerResolver = $layerResolver;
        $this->_queryFactory = $queryFactory;
        $this->resultPageFactory = $resultPageFactory;

        /* parent::__construct(
            $context
        ); */
    }

I get:

Argument 4 passed to Vendor\Module1\Controller\Result\Index::__construct() must be an instance of Magento\Framework\View\Result\PageFactory, instance of Magento\Search\Model\QueryFactory given, called in C:\xampp\htdocs\magento2x_5test\app\code\Vendor\Module2\Controller\Result\Index.php on line 36 and defined in C:\xampp\htdocs\magento2x_5test\app\code\Vendor\Module1\Controller\Result\Index.php on line 22

In controller module2 try to change:

parent::__construct($context,$catalogSession,$storeManager,$queryFactory,$layerResolver);

to the:

parent::__construct($context,$catalogSession,$storeManager,$resultPageFactory,$layerResolver,$queryFactory);

because you module1 controller constructor get this params in this order:

public function __construct(
    Context $context,
    Session $catalogSession,
    StoreManagerInterface $storeManager,
    \Magento\Framework\View\Result\PageFactory $resultPageFactory,
    Resolver $layerResolver,
    QueryFactory $queryFactory
) { ... }

Update:

In module 1 controller class change the line:

parent::__construct($context,$catalogSession,$storeManager,$resultPageFactory,$queryFactory,$layerResolver);

to the:

parent::__construct($context, $catalogSession, $storeManager, $queryFactory, $layerResolver);

Note:
clean the var/generation folder to see the changes.

  • After changing, Argument 4 passed to Magento\CatalogSearch\Controller\Result\Index::__construct() must be an instance of Magento\Search\Model\QueryFactory, instance of Magento\Framework\View\Result\PageFactory given, called in C:\xampp\htdocs\magento2x_5test\app\code\Vendor\Module1\Controller\Result\Index.php on line 26 and defined in C:\xampp\htdocs\magento2x_5test\app\code\Magento\CatalogSearch\Controller\Result\Index.php on line 53

make the constructor of your first controller class look like this:

class Index extends \Magento\CatalogSearch\Controller\Result\Index
{
public function __construct(
    Context $context,
    Session $catalogSession,
    StoreManagerInterface $storeManager,
    Resolver $layerResolver,
    QueryFactory $queryFactory,
    \Magento\Framework\View\Result\PageFactory $resultPageFactory
) {
    parent::__construct($context,$catalogSession,$storeManager,$queryFactory,$layerResolver);
    $this->resultPageFactory = $resultPageFactory;
}

and remove the constructor from the second class you posted.
