Instead of writing this file to a temp directory and referencing it
on the Gradle command line, the init script is now written to Gradle
User Home so that it is picked up automatically.
Instead of passing `--no-daemon` on the command line, the same
functionality is now acheived by writing a gradle.properties file
when initializing Gradle User Home.
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.
The `gradle-home-cache-includes` and `gradle-home-cache-excludes` parameters were initially implemented
as JSON string inputs. This makes these inputs non-idiomatic and easier to get wrong.
This change converts them to multi-line input parameters.
Fixes#106
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.
Unfortunately, doing this overloads the GitHub actions cache infrastructure
leading to failures and unpredictable results.
A later solution may re-implement artifact sharing for dependency jars
as well as jars within the `caches/jars-9` directory. But for now these
will be duplicated across each Gradle User Home cache entry.
Similar to wrapper distributions, these large files are common
to many Gradle User Home cache entries. Storing them separately removes
this redundancy from the Gradle User Home cache.
In the current model, each cached Gradle User Home could contain
a copy of one or more downloaded wrapper distributions. This results
in large cache entries which could easily lead to premature eviction.
With this change, wrapper dists are cached separately from the rest
of the Gradle User Home directory. The artifact file is replaced by
a marker file which allows the action to restore the artifact from
cache when the Gradle user Home cache is restored.
This will eliminate cache entries from previous workflow runs, allowing
us to test cache functionality in isolation. If the `CACHE_KEY_SEED` environment
variable is not set, this will have no impact.
- Do not restore cache when GUH exists
- Include RUNNER_OS in the cache key
- Do not save cache on exact hit
- Only save cache in the final post action
- Log before saving cache
