Moved reading of all input parameters into a common source: `input-params.ts`.
This centralized all input parameter reads, and allowed an improved implementation
of reading boolean parameters. In particular, the implementation now provides a default
value for a boolean input parameter that isn't declared for an action.
It appears that when restoring the Gradle User Home directory, certain empty
directories are being identified by Node as broken symlinks. This results in
`Error: ENOENT: No such file or directory` when attempting to resolve a Glob pattern.
By using the default behaviour of Globber (followSymbolicLinks && ignoreBrokenLinks),
these bad files no longer cause errors when saving the Gradle User Home to cache.
Fixes#408
The wrapper zip files are redundant, and not required after extraction.
Gradle 7.5+ will delete these automatically, but we delete them for older
versions to avoid caching the wrapper distributions twice.
Sinc the `gradle-home-cache-excludes` parameter does not support
wildcards, we remove them explicitly.
To save space, future versions of Gradle are likely to delete the downloaded distribution
after extracting it. See gradle/gradle#3605 and gradle/gradle#19495.
To cater for this we will now save/restore the extracted distribution rather than the
downloaded zip file.
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.
