Let's take a concrete example: your build script uses a generic `NpmTask` task to create a JavaScript bundle by delegating to NPM (and running `npm run bundle`).
This process is similar to a complex compilation task, but `NpmTask` is too generic to be cacheable by default: it just takes arguments and runs npm with those arguments.

The inputs and outputs of this task are simple to figure out.

	// Must be a JSON Path under `.status` or `.spec`.
	// Must be set to work with HorizontalPodAutoscaler.
	// The field pointed by this JSON path must be a string field (not a complex selector struct)
	// which contains a serialized label selector in string form.
