The command ekstep-content-sdk create <plugin name> creates the plugin, but editor plugin.js gets created with deprecated editor objects such as EkstepEditorAPI.
The plugin extends from another deprecated editor basePlugin EkstepEditor.basePlugin.
It would be really helpful if the code is updated to generate plugin.js file with valid objects, so the developers don't have to fix the code. Any new developer won't even know why it is not working.
