// An all-mode assert to verify that the given POSIX-style function

* A `File` — used as a file path
* A `FileCollection` or `FileTree` — all files in the collection are included in the copy
* A task — the files or directories that form a task's <<incremental_build.adoc#sec:task_inputs_outputs,defined outputs>> are included

In most cases, you will need to apply the changes from all versions that come after the one you're upgrading from.
For example, if you're upgrading from Gradle 4.3 to 5.0, you will also need to apply the changes since 4.4, 4.5, etc up to 5.0.

TIP: If you are using Gradle for Android, you need to move to version 3.3 or higher of both the Android Gradle Plugin and Android Studio.
