Heads up: I've drafted a couple PRs to improve the Iceberg build:
1. Enabling the Gradle build cache improves local build performance quite a bit, especially if you change from one branch to another. See https://github.com/apache/iceberg/pull/10602
2. Let the Iceberg build run against all Scala versions for each Spark version. This change, together with the existing `allModules` flag, allows building and releasing all artifacts in one shot. The defaults of the command-line build and IDE import are not changed. Given that there was already one Iceberg release that was broken due to wrong build artifacts, I think this change is justified. See https://github.com/apache/iceberg/pull/10606
3. Clean all artifacts: The Iceberg build can accumulate a lot of stuff on disk over time, this change "enhances" the Gradle `clean` task to get rid of this. See https://github.com/apache/iceberg/pull/10602
