Marks a property as specifying an input file for a task.

This annotation should be attached to the getter method in Java or the property in Groovy. Annotations on setters or just the field in Java are ignored.

This will cause the task to be considered out-of-date when the file path or contents have changed.

Note: To make the task dependent on the file's location but not its contents, expose the path of the file as an Input property instead.
