Description
The cache key generation does environment substitution in places that running
the commands doesn't. This causes issues if a command uses complex shell
substitutions. The cache key is generated even if caching isn't enabled. (See #1170)
This disables the cache key generation if caching is not enabled. This doesn't
fix the underlying issue, but limits it to when the cache is being used.
