Detect conflicts with Netbeans 11 built-in Gradle plugins to generate some helpful error to the user

[tcfurrer]

It would be nice if this plugin could somehow be enhanced to detect whenever the new Netbeans 11 "Gradle" or "Groovy And Gradle" plugins are installed, and warn the user that they will need to manually uninstall these plugins to avoid conflicts and various confusing bugs and broken functions.

Or, if it isn't possible to detect the plugins conflict, please at least document this clearly so that folks updating to Netbeans 11 don't waste time, and don't accidentally give up on this plugin thinking it isn't supported on Netbeans 11 (when actually it should work just as well there as it did on Netbeans 10, after manually uninstalling the conflicting new plugins).

Here is a link to the Netbeans ticket where they tried to help out with this issue, but the solution isn't quite good enough to prevent confusion: https://issues.apache.org/jira/browse/NETBEANS-1976
