Getting syntax error while upgrading to 2.4.4

Question

Hi I am getting the below error while upgrading Magento 2.3.4 to 2.4.4

MiBsyntax error, unexpected token "", expecting variable#0 /var/www/html/vendor/composer/ClassLoader.php(322): Composer\Autoload\includeFile('/var/www/html/v...'

Answer 1

I faced a similar issue so I tracked it back to below class and added a echo statement. The last class shown in the output was having a extra comma in the constructor.

Class /vendor/composer/ClassLoader.php Line 428

enter image description here

Answer 2

I found the issue , It was in my extension where there was space after \ in constructor.

Answer 3

In my case, there is new line after ResourceModel\ in the following path

/app/code/Company/MpVendorRegistration/Block/Adminhtml/Group/Edit/Tab/Attributes.php

the code was like bellow

use Company\MpVendorRegistration\Model\ResourceModel\
 VendorRegistrationAssignGroup\CollectionFactory as VendorRegistrationAssignGroupCollection;
use Company\MpVendorRegistration\Model\ResourceModel\
 VendorRegistrationAttribute\CollectionFactory as VendorRegistrationAttributeCollection;

It must be like bellow code

use Company\MpVendorRegistration\Model\ResourceModel\VendorRegistrationAssignGroup\CollectionFactory as VendorRegistrationAssignGroupCollection;
use Company\MpVendorRegistration\Model\ResourceModel\VendorRegistrationAttribute\CollectionFactory as VendorRegistrationAttributeCollection;

Answer 4

I get this error in my custom extension when ; (semicolon) was missing.

Answer 5

Try to run command using php version like:

/usr/bin/php8.1 bin/magento setup:di: compile

Instead of php bin/magento setup:di:compile
