Now that environment variable reads are auto-detected by Gradle 7.4,
we need a different mechanism to check that the configuration cache is
being used successfully.
MacOS runners are initialized with a Gradle User Home directory including
the `~/.gradle/notifications` directory. This was causing the action to skip
restoring the Gradle User Home on MacOS.
This fix limits the pre-existing GUH check to the `~/.gradle/caches` directory
which isn't pre-initialized in the runner.
Fixes#155
Improves logging for caching, and adds 2 experimental cache options:
- `gradle-home-cache-strict-match`: Avoid re-using a Gradle Home cache entry written by a different job. Only cache entries written by the current Job will be used.
- `cache-write-only`: Do not restore existing cache entries, but still save cache entries in post-action. Fixes#141.
There may be cases where it a "fresh" cache entry would be beneficial,
for example if the Gradle User Home cache entry grows over time.
This setting would run the build as if no prior cache entry exists.
By default, the action will attempt to restore a Gradle User Home
cache entry from a different set of matrix inputs (or a different Job entirely)
if an existing entry is not found for the current Job (including matrix inputs).
By specifying the experimental `gradle-home-cache-strict-match` parameter, a user
can avoid this fuzzy matching and ensure that a job execution starts with an
empty Gradle User Home if no entry from a prior execution is found.
Fix Build Scan capture when cache is disabled
With the change to use init-scripts to inject Build Scan capture, this functionality broke when caching was disabled and Gradle User Home wasn't initialized.
This PR fixes a couple of issues and ensures that the Gradle User Home is initialized even when it is not restored from the GitHub Actions cache.
Fixes#138Fixes#139
This change to the integration tests should properly isolate multiple runs of the same job.
Previously, some jobs would fail if you attempted to re-run them via the UI, because the cache
entries would be re-used from the previous run.
Instead of using a fallback strategy to locate a configuration-cache entry
based on the current job and git SHA, these entries are now keyed based on their
file content with the keys persisted in the primary Gradle User Home entry.
This removes the chance of having a configuration-cache entry restored that is
incompatible with the restored Gradle User Home state, and makes the logic easier
to understand.
This change involved a fairly major refactor, with the CacheEntryExtractor being
split out from the primary cache implementation, and adding a separate extractor
implementation for configuration-cache.
