Ionic 3 Failed to restore “com.attendee.barcodegenerator” in config.xml


In the Ionic project, I removed the attachment that I had previously attached. But when I build the project I get an error. I mentioned the fault below. I could not find a solution. I delete the necessary places in Config.xml, but this line is added again when it is rebuilt. I’m glad you found a solution to the problem. Thank you

Discovered plugin "com.attendee.barcodegenerator" in config.xml. Adding it to the project

Probably this is either a connection problem, or plugin spec is incorrect.
Check your connection and plugin name/version/URL.
