This issue is present in only Kotlin/Kotlin (Gradle) file source sets that I know of with the ktlint formatter.

When a source file is changed, the license doesn't reflect the changes and marks the file as an OK state, which should update the license content if it was changed.

A reproduction repository can be seen in auguwu/spotless-kotlin/repro. Just run ./gradlew spotlessApply.

Expected Result

/**  * some example of license content here  * Copyright (c) 2023  */ import kotlin.TODO fun main(args: Array<String>) { println( "we do a little" + "trolling", ) TODO("this function is a work in progress!") } 

Actual Result

import kotlin.TODO fun main(args: Array<String>) { println( "we do a little" + "trolling", ) TODO("this function is a work in progress!") }
