Description
Add
ci.opensearch.org/maven2/cache mirror abovemavenCentral()in all repository blocks to reduce direct calls to Maven Central and avoid HTTP 429 Too Many Requests throttling from CI builds.Maven Central has imposed new rate limiting restrictions (details) which cause CI builds to fail with 429 errors when resolving dependencies. This cache mirror serves as a proxy that caches artifacts for 24 hours, dramatically reducing call count to Maven Central.
