==== Duplicates strategy

Gradle 7 now fails when a copy operation (or any operation which uses a `org.gradle.api.file.CopySpec`) encounters a duplicate entry, and that the duplicates strategy isn't set.
Please look at link:{javadocPath}/org/gradle/api/file/CopySpec.html#setDuplicatesStrategy-org.gradle.api.file.DuplicatesStrategy-[the CopySpec docs] for details.

 * You can no longer pass `null` as the configuration action of link:{javadocPath}/org/gradle/api/file/CopySpec.html#from-java.lang.Object-org.gradle.api.Action-[CopySpec.from(Object, Action)].
 * For better compatibility with the Kotlin DSL, link:{javadocPath}/org/gradle/api/file/DuplicatesStrategy.html[CopySpec.duplicatesStrategy] is no longer nullable. The property setter no longer accepts `null` as a way
