2. Using a task as a copy source, i.e., as an argument to `from()`, won't create an automatic task dependency between your task and that copy source.
As such, if you use the `copy()` method as part of a task action, you must explicitly declare all inputs and outputs to get the correct behavior.

The following example shows how to work around these limitations using the <<incremental_build.adoc#sec:task_input_output_runtime_api,dynamic API for task inputs and outputs>>:
