Hi,

It seems like the plugin.manager.config_entity_migration service has been removed in the latest version of migrate_plus. Why was this done? Is there a replacement for this? I was using this to have a block of available migrations for a node so that a user could trigger the migrations from the UI when they wish. (see my screenshot).

I was using it like this:

  $manager = \Drupal::service('plugin.manager.config_entity_migration');
  $plugins = $manager->createInstances([]);
  $active_migrations = array();
  $flipped = array_flip($migrations);
  foreach ($plugins as $id => $migration) {
    if (in_array($id, $migrations)) {
      $active_migrations[$id] = $flipped[$id];
    }
  }

The trick for me is finding the migrations associated with this node. (One node can have 0 to 5 migrations) and so I determine which are enabled and then loop through the migration entity configs to find matches. How can this be done now?

Thanks,
Donovan

For me this error also appears after upgrading from beta2 to beta4, then going to admin/structure/migrate/manage/default/migrations. The on-screen error is a white screen with "The website encountered an unexpected error. Please try again later."; the watchdog logs contain the actual PHP error:

Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service "plugin.manager.config_entity_migration". in Drupal\Component\DependencyInjection\Container->get() (line 157 of /var/www/core/lib/Drupal/Component/DependencyInjection/Container.php).

Might be related. I am getting this in watchdog when I try to 'List igrations' from /admin/structure/migrate :
Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service "plugin.manager.config_entity_migration". Did you mean this: "plugin.manager.commerce_entity_trait"? in Drupal\Component\DependencyInjection\Container->get() (line 157 of /var/www/html/web/core/lib/Drupal/Component/DependencyInjection/Container.php).

Looks like the issue in #2 and #3 is a regression from #2752335: Properly integrate configuration-entity-based migrations with the core plugin manager. As far as the original issue I think we can now create instances through the normal drupal service like this 

  $pluginManager = \Drupal::service('plugin.manager.migration');
  $instance = $pluginManager->createInstance('some_migration');

#4 worked for me, or at least something similar, essentially changing plugin.manager.config_entity_migration to plugin.manager.migration

Yes, when we implemented a deriver to pull in config-entity-based migration we no longer needed plugin.manager.config_entity_migration, so we deprecated it and later removed it.
