Problem
As far as I understand, go requires a /v2 suffix after a major version bump. Also see this.
If you want met to submit a PR, please let me know, but I think this is better handled by maintainers. Also my understanding of go is limited so this problem description might not be 100% accurate.

If you have already set
FROM docker.io/apache/answer:2.0.0 AS answer-builder, then you don't actually need to setARG ANSWER_MODULE=github.com/apache/[email protected]since you're already building on top of version 2.0.0. That said, I’ll continue to follow up on this issue to see how it should be handled.
