Hi @jbonofre, here are my changes, if you want to use anything from it. Please let me know if you have any questions or need any help: happy to chat. Thanks!

At first glance, the change is good. However, I have two comments:

1. Did you check a release is still valid ? I see a change in the generated artifacts.
2. As I said in the GitHub Issue, Gradle 9.x requires JDK17+. AFAIR, not all parts of Iceberg are ready to JDK17+ AFAIR. We have to double check and verify with the community here.

nit: I would add just a note to explain why processors plugin can be removed.

I don't think iceberg-api is required here (`iceberg-core should be enough).

we have to keep sourceJar, javadocJar, and testJar here as it's required to have a valid release.
