A build cache key is assigned to each cacheable task when running with the build cache enabled and is used for both loading and storing task outputs to the build cache.
The following inputs contribute to the build cache key for a task:

* The task implementation
* The task action implementations
* The names of the output properties
* The names and values of task inputs
