To save space, future versions of Gradle are likely to delete the downloaded distribution
after extracting it. See gradle/gradle#3605 and gradle/gradle#19495.
To cater for this we will now save/restore the extracted distribution rather than the
downloaded zip file.
This is a pure refactor, moving from a separate .cache file per bundle to a single cache-metadata.json file describing all bundles. Instead of storing cache metadata in a separate .cache file per artifact bundle, all of the metadata is now stored in a single `.json` file.
This will make it easier to implement more flexible artifact-caching strategies, such as caching each wrapper zip separately.
* Always include cache protocol version in cache key
* Store all cache metadata in a single JSON file
* Rename cache-metadata file and bump protocol version
* Polish and documentation
Failures to store cache entries should not fail the action or the Job.
This fix attempts to catch and log any unexpected errors that occur when
saving cache entries.
Fixes: #119Fixes: #120
- Warn and continue on failure to restore a Gradle distribution from cache
- Warn and continue on failure to save a Gradle distribution to cache
- Extract common functionality for consistent handling of cache failures
Fixes#116
When caching is too fine-grained, an excessive number of cache
requests can result in HTTP 429 errors due to rate limiting.
By caching all artifacts of a particular type in a single entry
we hope to mitigate this, at the expense of some reduction in
cache space optimization.
This change also adds caching for all dependency jars, as well as
instrumented jars in the 'caches/jars-X' directory.
