If the verification task has no "external inputs" and produces file outputs, it can quite well be worth to enable caching, except if the verification task is so fast that it is faster to redo the verification than to get the result from the cache and unzip it.

If your task does not have file outputs anyway, it makes no sense to mark it cacheable as there is nothing to cache.

In that case just making it able to be up-to-date might be good if there are no external inputs, by having

outputs.upToDateWhen { true }

.
