Failed to apply plugin

Hello,

Trying this plugin out on a existing project, I'm having this error

> gradle clean assemble

I've tried with gradle 7.0.2 and 6.9, same error.
JDK is 15

If it helps, I'm attaching the output with the --stacktrace option

Hi, are you trying to apply the plugin inside build.gradle.* file?

It should be applied within settings.gradle.*
For instance (note you need to add version depending on the way you manage plugin versions): https://github.com/pgjdbc/pgjdbc/blob/45a771fccd77c1211d8638111ee3e9934849b781/settings.gradle.kts#L36

Missed that part of the documentation that needed to be applied in the settings.gradle.*. It's working now 👍

The only two minor changes I had to do to the configuration, in our case using settings.gradle.kts

buildCache {
    local {
        isEnabled = false   // if left as `enabled`, Cannot access 'enabled': it is invisible (private in a supertype) in 'DirectoryBuildCache'
    }
    remote<com.github.burrunan.s3cache.AwsS3BuildCache> {
        //...
        isPush = isCiServer   // if left as `push`, Cannot access 'push': it is invisible (private in a supertype) in 'AwsS3BuildCache'
    }
}

This change works with gradle 6.9 and 7.0.2
