<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>Plugin manager services in core and contrib follow the naming pattern 'plugin.manager.foo'.</p>
<p>e.g.</p>
<pre> plugin.manager.filter:<br> class: Drupal\filter\FilterPluginManager<br> parent: default_plugin_manager</pre><p>The plugin manager service here is called localgov_waste_collection.data_provider_manager.</p>
<p>This means that modules like Plugin and Module Builder don't detect it.</p>
