I'm trying to re-compile using

php bin/magento setup:di:compile

But when I run this command, I get:

Fatal error: Cannot use 'Void' as class name as it is reserved in /var/www/html/magento/vendor/magento/module-sales/Controller/Adminhtml/Order/Invoice/Void.php on line 9

I am running PHP 7.1.0-alpha.

I don't think Magento 2 is yet compatible with php 7.1-alpha, but this is an alarm signal.
I think you should report this on github.
It could be an issue in the near future,

Here is how to fix it:

  1. edit vendor/magento/module-sales/etc/webapi.xml line 112:

    - <route url="/V1/invoices/:id/void" method="POST">
    + <route url="/V1/invoices/:id/voidInvoice" method="POST">
  2. edit vendor/magento/module-sales/Block/Adminhtml/Order/Invoice/View.php line 242:

    - return $this->getUrl('sales/*/void', ['invoice_id' => $this->getInvoice()->getId()]);
    + return $this->getUrl('sales/*/voidInvoice', ['invoice_id' => $this->getInvoice()->getId()]);
  3. edit vendor/magento/module-sales/Block/Adminhtml/Order/Creditmemo/View.php line 183:

    - return $this->getUrl('sales/*/void', ['creditmemo_id' => $this->getCreditmemo()->getId()]);
    + return $this->getUrl('sales/*/voidCreditmemo', ['creditmemo_id' => $this->getCreditmemo()->getId()]);
  4. edit vendor/magento/module-sales/Controller/Adminhtml/Order/Invoice/Void.php line 9:

    - class Void extends \Magento\Sales\Controller\Adminhtml\Invoice\AbstractInvoice\View
    + class VoidInvoice extends \Magento\Sales\Controller\Adminhtml\Invoice\AbstractInvoice\View
  5. edit vendor/magento/module-sales/Controller/Adminhtml/Order/Creditmemo/Void.php line 10:

    - class Void extends \Magento\Backend\App\Action
    + class VoidCreditmemo extends \Magento\Backend\App\Action
  6. rename




  7. rename

  • in Magento Enterprise mv vendor/magento/module-reward/Model/Action/Creditmemo/Void.php vendor/magento/module-reward/Model/Action/Creditmemo/VoidCreditmemo.php in line 8 change class Void to class VoidCreditmemo – marcinsdance Jan 25 at 11:40

This is no longer an issue for Magento 2.2 - Magento 2.1 was not PHP7.1 compatible.
