Am getting this Error while Compiling during upgrade from 2.1.10 to 2.2.3.

  Class \Magestore\GiftVoucher\Api\GiftVoucherProduct\GiftvoucherProductRepos
  itoryInterface does not exist

I checked, Every folder is there i.e. Magestore, GiftVoucher, Api, GiftVoucherProduct is there. Inside 'GiftVoucherProduct' there is a file named 'GiftvoucherProductRepositoryInterface.php'

Please anyone resolve this error.

I have done few fixes which are mentioned on net, but nothing worked out.

ReflectionException is occured when some class or some interface is not found.

it is generally coming from generated directory.

Below is the way to resolved the error

Run below commands in sequence from your terminal :

  • rm -rf generated
  • rm -rf var/cache , rm -rf var/page_cache , rm -rf var/view_processed
  • php bin/magento setup:upgrade
  • php bin/magento setup:di:compile
  • php bin/magento setup:static-content:deploy -f
  • php bin/magento cache:clean
  • php bin/magento cache:flush
