All that means is essentially all of those classes are available in the plug-in runtime environment - in other words, if your plugin uses one of those packages/classes, you don&#39;t need to include an external JAR inside the plugin JAR. Classes *not found* on that list, will need JARs within the plugin JAR.<br /> <br /> I would recommend checking out this article for guidance on creating a plugin and what external files you need - <a href="https://docs.appian.com/suite/help/18.3/Custom_Smart_Service_Plug-ins.html#creating-and-deploying-the-plug-in">docs.appian.com/.../Custom_Smart_Service_Plug-ins.html</a><div style="clear:both;"></div>
