That parameter tells Gradle that the action only wants to process the changed inputs.

In addition, the task needs to declare at least one incremental file input property by using either link:{javadocPath}/org/gradle/work/Incremental.html[`@Incremental`] or link:{javadocPath}/org/gradle/api/tasks/SkipWhenEmpty.html[`@SkipWhenEmpty`]:
