Code Review

This pull request updates the Iceberg version to 1.11 and introduces a configurable Maven mirror for Iceberg JARs. The reviewer recommends using the full semantic version 1.11.0 for proper artifact resolution and suggests defaulting the mirror URL to the standard Maven repository instead of hardcoding a staging URL to improve maintainability.

The version 1.11 appears to be incomplete given the PR title "try 1.11.0 rc1". Apache Iceberg typically follows semantic versioning (x.y.z). If this is for the 1.11.0 release candidate, the version should likely be 1.11.0 to correctly resolve the artifact paths in the Maven repository.

ARG ICEBERG_VERSION=1.11.0

Hardcoding a specific staging repository URL makes the Dockerfile less flexible and harder to maintain once the release is finalized. It is better to define ICEBERG_MAVEN_MIRROR with a default value pointing to the standard mirror and override it via a build argument (--build-arg) when testing release candidates.

ARG ICEBERG_MAVEN_MIRROR=${MAVEN_MIRROR}
