The following cleanup strategies are applied periodically (by default, once every 24 hours):

- Version-specific caches in all `caches/<GRADLE_VERSION>/` directories are checked for whether they are still in use.
+
If not, directories for release versions are deleted after 30 days of inactivity, and snapshot versions after 7 days.
- Shared caches in `caches/` (e.g., `jars-*`) are checked for whether they are still in use.
