  • Enum Constant Details

    • MAVEN_CENTRAL_MIRROR

      public static final DependencyRepository MAVEN_CENTRAL_MIRROR
      Maven Central mirror repository.

      This is used to reduce the load on repo.maven.org.

      Although Maven Central is technically a CDN, it is meant for developer use, not end-user products. It is trivial and not very expensive for us to provide a mirror, which will absorb any traffic caused by LP.

      LuckPerms will fallback to the real-thing if the mirror ever goes offline. Retrieved content is validated with a checksum, so there is no risk to integrity.
