This is root level gradel -

And i got this error after running. Somebody please explain the fix i’ve been stuck here for hours. (I tried everything ChatGPT suggested hence this is my last resort !)

Why is this the “last resort”?
You didn’t try any helpful resource yet.
ChatGPT is not good at giving correct answers.
I is just good at giving answers that look correct, but often he made up the most things.

Besides that its database is more than 2 years old, which is ages in computer time,
ChatGPT is only good for things you could do yourself but are too lazy. (The good kind of lazy, not the bad one).
You always have to understand what it did, and fix the non-sense it produces like calling methods on APIs that never existed and so on.

ChatGPT answers are also not banned for nothing from sites like StackOverflow.

Regarding your problem, the error is quite meaningful.
It tells you that you tried to apply a plugin that it cannot find in the configured plugin repositories which is only the default, the Gradle Plugin Portal, where this plugin is not present.

Add

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
    }
}

to your settings script and the plugin will be found.

well i don’t know if this helped OP but i had my pluginManagment just like that and it’s still not working… so i turn it off and on again hopeing it would help, the problem was still there obviously but now there was a suggestion to " turn off offline mode " wich i didn’t know i had turned on in the first place, accept the helping hand and next thing my problem was no more… i don’t have a well based understanding of the why’s this worked but if someone else has this problem maybe this is your solution, hope it helps at least someone. Good luck y’ll !!!

But when you had it like I showed and got the error, you probably got both repositories listed, the Gradle Plugin Portal, and the Google repository. In that case, it could indeed be the offline mode. But for OP it showed only the GPP, so Google was definitely missing in the configuration. :slight_smile:
