Build Error When Enabling WebSocketServer Plug-in in Monaca

When I enable the WebSocketServer plug-in for Cordva 3.5.1 in Monaca and build the Android app, the following error occurs:

A similar error occurred when HttpServer was enabled for the same Cordva 3.5.1 but there was no problem when Share was enabled.
Do I need any other settings to use WebSocketServer or HttpServer?

This is my first time using Monaca, so I'm sorry if it's a rudimentary mistake, but I'd appreciate your guidance.
