Magento 2.3.3 Fails on magento setup:di:compile with an error mentioning InvoiceFlexFieldProcessorInterface

Question

I have installed the new Magento 2.3.3 version.

After I have run the command:

php bin/magento setup:di:compile

I have Faced the following error:

PHP Fatal error: Interface 'Vertex\Tax\Model\Flexfield\Processor\InvoiceFlexFieldProcessorInterface' not found in /var/www/html/magento2/vendor/vertex/module-tax/Model/FlexField/Processor/OrderCurrencyGetterProcessor.php on line 24

Please refer the following screenshot:

How to solve this.

Thanks in Advance.

Answer 1

Go to Below File

/vendor/vertex/module-tax/Model/FlexField/Processor/OrderCurrencyGetterProcessor.php

At the end of the "use" clauses in

add the following two lines:

use Vertex\Tax\Model\FlexField\Processor\InvoiceFlexFieldProcessorInterface;
use Vertex\Tax\Model\FlexField\Processor\TaxCalculationFlexFieldProcessorInterface;

and run again below command

php bin/magento setup:di:compile

Answer 2

I run into the same problem. It seems only a speeling problem: https://github.com/magento/magento2/issues/24930#issuecomment-543949135

So it is better to change only the namespace spelling without adding the two use-lines:

namespace Vertex\Tax\Model\FlexField\Processor;

FlexField instead of Flexfield

It could make a difference for external functions that use this class.

If like me you can't edit the file (because our CD will fail) follow these steps:

1. In the root of your project, create a directory patches/composer
2. Create a file called vendor-vertex-compilation-issue.diff
3. In your composer.json add this to the list of "require" "cweagans/composer-patches": "1.6.7"
4. Still in your composer.json add this to the extras

       "patches": {
           "vertex/module-tax":{
               "MAGETWO: vendor vertex compilation issue": "patches/composer/vendor-vertex-compilation-issue.diff"
           }
       }

5. Put the following content into the vendor-vertex-compilation-issue.diff file that you created earlier

diff --git a/Model/FlexField/Processor/OrderCurrencyGetterProcessor.php b/Model/FlexField/Processor/OrderCurrencyGetterProcessor.php
index 6fb4944..86a66f4 100644
--- a/Model/FlexField/Processor/OrderCurrencyGetterProcessor.php
+++ b/Model/FlexField/Processor/OrderCurrencyGetterProcessor.php

  */

-namespace Vertex\Tax\Model\Flexfield\Processor;
+namespace Vertex\Tax\Model\FlexField\Processor;

 use Magento\Framework\Exception\NoSuchEntityException;
 use Magento\Quote\Api\CartRepositoryInterface;

6. run composer install

This should install the vertex module and apply the patch to the module and then you can go on with compiling Magento as you normally would

UPDATE

As of Magento 2.3.4, the vertex/module-tax has been upgraded to 3.3.0 (from 3.2.0) and the issue is corrected and the patch no longer needed

Answer 4

Goto file:

/vendor/vertex/module-tax/Model/FlexField/Processor/OrderCurrencyGetterProcessor.php

Add missing line:

use Vertex\Tax\Model\FlexField\Processor\TaxCalculationFlexFieldProcessorInterface;

after

use Vertex\Tax\Model\FlexField\FlexFieldProcessableAttributeFactory;

& Try setup-upgrade & di-compile once again.

For more info you can check module's di.xml file for abstract-interface mapping.

Answer 5

If you aren't using the Vertex Tax module in your installation, you can use the replace key in the composer JSON so the module files don't even get pulled into your installation.

// composer.json
{
  "name": "magento2/testing",
  "type": "project",
  "require": {
    "magento/product-community-edition": "2.3.3",
    ...
  },
  ...
  "replace": {
    ...
    "vertex/module-tax": "*", // add other modules to exclude here
    ...
  }
}

This is only a solution if you know your users won't want to use the vertex tax module, instead of patching it.
