Custom CK Editor toolbar is registered but not displayed

Issue

• We followed this blog post to create a custom CKEditor 4 module in workspace.
• We can see that CKEDITOR.plugins.registered but, we are not able to see it on the CK Editor toolbar UI in Liferay 7.4 portal.

Environment

• Quarterly Releases

Resolution

• The blog post was written 4 year ago, since then several changes have been made to CK Editor 4.  

• In the CKEditorCustomPluginConfigContributor.java file, the property "editor.name=ckeditor_classic" has to be added to the @Component properties for the buttons to appear.

  @Component(immediate = true, property = { "editor.name=ckeditor", "editor.name=ckeditor_classic",
  "service.ranking:Integer=1000" }, service = EditorConfigContributor.class)

Additional Information

• Add custom plugin to CKEditor toolbar
