Problem/Motivation

I'm using the Drupal component "drupal/core-annotation" in a custom project and after I updated all its dependencies and tried to run the project, I got the following error:

Fatal error: Uncaught Error: Interface "Drupal\Component\ClassFinder\ClassFinderInterface" not found in /myproject/vendor/drupal/core-annotation/Reflection/MockFileFinder.php:15

Drupal\Component\Annotation\Reflection\MockFileFinder extends Drupal\Component\ClassFinder\ClassFinderInterface, but "drupal/core-class-finder" is not listed as dependency in the composer.json of "drupal/core-annotation".

Steps to reproduce

  1. Create a composer based project that depends on "drupal/core-annotation".
  2. Create an annotation class.
  3. Create a plugin interface extending \Drupal\Component\Plugin\PluginInspectionInterface.
  4. Create plugin base class extending \Drupal\Component\Plugin\PluginBase and implementing the just created interface.
  5. Create a plugin manager class that sets the discovery property to an instance of \Drupal\Component\Annotation\Plugin\Discovery\AnnotatedClassDiscovery and the factory property to an instance of \Drupal\Component\Plugin\Factory\DefaultFactory. Pass the plugin interface name as second parameter when constructing DefaultFactory.
  6. Create a plugin class that uses annotation. Name it for example 'bar'.
  7. Try to instantiate the plugin as follows:
    \Drupal\Component\FileCache\FileCacheFactory::setPrefix('foo');
$manager = new \MyProject\PluginManager();
$manager->createInstance('bar');

Proposed resolution

Add "drupal/core-class-finder" to the composer.json of "drupal/core-annotation".
