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.
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.
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
- 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.
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.
