To implement this, you might inject a print statement:

====
include::sample[dir="snippets/performance/resolveAtConfigurationTime/kotlin",files="build.gradle.kts[tags=copy]"]
include::sample[dir="snippets/performance/resolveAtConfigurationTime/groovy",files="build.gradle[tags=copy]"]
====

                        attributes {
                            attribute(artifactType, 'green')
                        }
                    }
                }

                tasks.register("resolveAtConfigurationTime").configure {
                    inputs.files(configurations.green)
                    configurations.green.each { println it }
                    doLast { }
                }
