In this context, properties in Gradle act as references to the actual values behind them, allowing Gradle to track inputs and outputs between tasks.

For the input of our task, we use a `DirectoryProperty` from Gradle.
We annotate it with `@InputDirectory` to indicate that it is an input to the task:
