- Cache is separate from (but similar to) the wrapper distribution cache
- New 'distributions-cache-enabled' flag controls caching of all downloaded distributions
(including wrapper distributions)
- Deprecated the 'wrapper-cache-enabled' flag for removal in v2
Prior to this change, the wrapper cache contained both the downloaded zip
file as well as the exploded wrapper dir. Only the zip file is required,
as Gradle will automatically detect and unpack.
