How to configure NetBeans 11 for CodeIgniter 3.1.10 ?

Salut ! I personnally use NetBeans 11 as main IDE, but it's seems that the plugin for CI is abandoned (not touched since 2016 on github). I still tried to install by following this tuto : Customize Netbeans IDE for CodeIgniter. When I chose the "Base file" it said "Unsupported version".
But version of what ?
Is it the IDE that isn't supported by the plug-in (NetBeans 11) ?
Or is it the CI version that isn't supported by the plugin (CI 3.1.10) ?
The plug-in itself seems to be install (at least partially) because I have the menu and the framework referenced in the IDE.

If it's impossible to use CI on Netbeans what alternative IDE can I use ?
