If you apply the `greetings` plugin, you can set the convention in your build script:

====
include::sample[dir="snippets/plugins/greeting/kotlin", files="app/build.gradle.kts[]"]

// tag::use-plugin[]
plugins {
    application
    id("greetings")
}
// end::use-plugin[]

greeting {
    message = "Hello from Gradle"

// tag::use-plugin[]
plugins {
    id 'application'
    id('greetings')
}
// end::use-plugin[]

configure(greeting) {
    message = "Hello from Gradle"
