Previously, the action was restoring/saving the configuration-cache data for each
step that applied the action. In order to support Gradle invocations that are _not_
managed by the action, the configuration-cache restore is now performed in the initial
action step, and save is performed in the final post-action step.
The build root directories are recorded for each invocation via an init script.
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
- 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
Instead of tracking a single 'fully-restored' flag, track the restore status of each
cache entry restore. If any of these are requested but not restored, then the overall
Gradle User Home cache is not fully restored.
Added special handling for the case when zero artifact bundles are set: this is used
in tests to simulate a not-fully-restored state.
Previously, only .jar files were bundled, with other files (modules, POMs, zips, etc)
being left in Gradle User Home. All downloaded files are now included in the bundle.
Fixes#100
Leaving the `.lock` and `.receipt` files lying around was causing
issues when the actual jar files were not restored. Now the entire
directory will either be missing, or completely restored.
Attempt to capture as much context as possible about the job run
to generate a unique cache key. Unfortunately much of the matrix context
is not available to the action implementation.
Cache keys have a hard limit of 512 characters, so we need to ensure that we don't generate a key longer than this.
- Remove excess whitespace
- Truncate to 400 characters
Fixes#70
