The `GreetingPlugin` can now be applied in other subprojects' builds by using its ID:

include::sample[dir="snippets/plugins/greetingPlugin/kotlin",files="app/build.gradle.kts[tag=use-plugin]"]

    id("gradlebuild.lifecycle")                  // CI: Add lifecycle tasks to for the CI pipeline (currently needs to be applied early as it might modify global properties)
    id("gradlebuild.generate-subprojects-info")  // CI: Generate subprojects information for the CI testing pipeline fan out
    id("gradlebuild.cleanup")                    // CI: Advanced cleanup after the build (like stopping daemons started by tests)
