Using a single cache entry for all files of a type is necessary to avoid
overloading the cache service. However, this mechanism is not very efficient
for certain artifacts like wrapper zips and generated-gradle-jars, where the
same individual files are often shared between different jobs.
With this change, any configured file patterns that do not end in '*' will
be cached as individual files. At this time this includes downloaded wrapper
zips and generated-gradle-jars.
Fixes#78
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
Instead of writing the URL to a file on disk, reading it later and
using the Actions API to record the output parameter and write the notice,
these things are now done directly via Actions commands emitted directly
from the init script.
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.
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
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
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
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.
Instead of parsing the log output, we instead register a
buildScanPublished listener and record the build scan URL
to a file. This file is subsequently read to report the
build scan URL.
Fixes#30
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.
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.
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.
The Gradle daemon is not useful for ephemeral builds, and the process
can hold file locks which interfere with cache entry generation.
In the case where multiple Gradle invocations occur in the same job,
we could provide a way for users to override this behaviour, taking care
of stopping any daemon process at the end of the job.
- 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
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
This makes the version alias match other places where we reference a release candidate version.
The 'rc' alias is still supported, but emits a deprecation warning.
- 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.
- Provide a more useful error message when no Gradle wrapper can be located,
and 'gradle-version' or 'gradle-executable' is not used.
- Add test for case where wrapper is missing.
This isn't really a "test" per-se, but this failing build invocation makes it
easy to verify the GitHub action behaviour when the build is misconfigured.
This is relevant if you run this action several times in a single job.
This prevent doing unnecessary work starting with the second job using the action.
This prevent droping dependencies downloaded by the first job using the action.
This prevent Windows agents to fail unlinking already existing files.
