# The immutable Maven cache also contains Central's mutable namespace index.
# Resolver can reuse that local index for the rest of the day, even after a
# new namespace is published, producing warnings that fail our strict policy.
# Remove only the auto-discovered Central index before any Maven build starts;
# its next process downloads a fresh index while retaining cached artifacts,
# user-defined filters, and our strict Maven warning policy.
