use GCS mirror for Maven, fix benchmarks version, other small changes by jameslamb · Pull Request #166 · NVIDIA/cuvs-lucene

jameslamb · 2026-06-24T16:36:20Z

Fixes #145

Contributes to rapidsai/build-planning#297

The root cause of #145 appears to be that we were getting rate-limited by Maven Central. Similar to NVIDIA/cuvs#2253, this proposes fixing that by using the same read-only Maven mirror that Apache Orc, Lucene, Spark and others use in their builds (https://storage-download.googleapis.com/maven-central/index.html).

Other changes:

fixes microbenchmarks version (was still 26.02 because it used the cuVS pattern for version replacement)
adding default mvn options to request packages more slowly and wait longer between retries
updating all pre-commit hooks w/ pre-commit autoupdate
adding check-xml hook to validate that pom.xml are valid XML docs
reformatting READMEs per https://yihui.org/en/2021/06/markdown-breath/

+-Daether.connector.basic.downstreamThreads=1
+-Daether.transport.http.retryHandler.count=5
+-Daether.transport.http.retryHandler.interval=10000
+-Dmaven.wagon.http.retryHandler.count=5


See NVIDIA/cuvs#2253 (comment) for an explanation of these flags.

I believe comments are not allowed in this file because its contents are passed literally to mvn.

Thanks James! 🙏

Had a couple questions below. Most can be handled separately

Would just double check the copyright one

What is the context behind this addition?

It was added automatically by the verify-codeowners pre-commit hook.

This became the default in February (rapidsai/pre-commit-hooks#120) based on internal conversations about the preferred form.

It's showing up here now because:

that change went into rapidsai/pre-commit-hooks v1.5.0 and this repo was using an older version until this PR

the hook only changes copyright statements on files as they're touched, not all at once, and this PR touches that file

If you have questions about the history behind rapidsai/pre-commit-hooks#120 you can talk to @KyleFromNVIDIA . But this has been the standard across RAPIDS for a few months now.

Do we need this in other files then?

A few files here changed, but not all have this particular wording

I don't know why this project doesn't include .xml files in its configuration for that hook. It's probably unintentional, I'd be happy to approve a PR adding them if you want to put one up.

Is there anywhere else that needs this change?

Possibly needs changes in ci/release/update-version.sh?

Possibly needs changes in ci/release/update-version.sh?

I don't think so. The file was covered already, the pattern was just wrong.

https://github.com/rapidsai/cuvs-lucene/blob/5e438035c673a33fef05517718439a3b8e6a36f2/ci/release/update-version.sh#L109-L11

bash ./ci/release/update-version.sh '26.10.00' --run-context=main git grep -E '25\.|26\.' # (same result as above, but with all 26.08 changed to 26.10)

/merge

The merge of origin/main (c840848) combined two independently-added <repositories> blocks: the GCS-mirror + Maven Central block from NVIDIA#166 (releases only, snapshots disabled) and the central-snapshots block from the snapshot-build change (snapshots enabled). Two <repositories> tags is invalid XML, so the POM failed to parse. Consolidate both into a single <repositories> block, preserving all three repositories: the GCS mirror and Maven Central for releases, and central-snapshots for snapshot resolution.
