Using convention plugins defined in included builds

Regarding convention plugins which are defined in included builds. How can they be used in other sub-projects and root project?

The examples only show how they can be used when inside buildSrc.

I have in build.gradle

plugins {
	id 'leo.build-conventions'
}

with leo/build-conventions/src/main/groovy/leo.build-conventions.gradle. build-conventions is an included build in leo's settings.gradle. Also build-conventions project has a build.gradle and settings.gradle files. But I get:

Build file 'C:\Users\sirin\GitHub\leo\build.gradle' line: 2

Plugin [id: 'leo.build-conventions'] was not found in any of the following sources:

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:
org.gradle.api.plugins.UnknownPluginException: Plugin [id: 'leo.build-conventions'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Included Builds (None of the included builds contain this plugin)
- Plugin Repositories (plugin dependency must include a version number for this source)

Also build-conventions have other projects like java-conventions, common-conventions, etc. which are also included builds in build-conventions project.
