Wire cuOpt Java bindings into the shared maven-publish workflow - #1970
ramakrishnap-nv wants to merge 22 commits into
Conversation
Adds a java-maven-publish job that calls rapidsai/shared-workflows' maven-publish.yaml against the Maven-repository-layout artifact java-static-gather already assembles (rapidsai/build-infra#379). The shared workflow signs the bundle and routes it to Maven Central (release tags) or the Sonatype snapshot repo (everything else). Requires GPG_PRIVATE_KEY, GPG_PASSPHRASE, MAVEN_DEPLOY_TOKEN secrets and a MAVEN_DEPLOY_USERNAME repo/org variable to actually publish; those still need to be provisioned separately.

Can you try temporarily replicating this in the pr.yaml file and testing that the workflow works end-to-end?

Done in 5a8e48f: added java-static-gather-tmp (runs for real) and java-maven-publish-tmp (if: false — GitHub Actions still validates the reusable-workflow call shape/secrets, but it can never actually execute a publish regardless of repo credentials) to pr.yaml. Will revert this before merge.

Job run: https://github.com/NVIDIA/cuopt/actions/runs/35918761360/job/109027460526 (java-maven-publish-tmp on commit 67f0ebe). It succeeded end-to-end and published com.nvidia.cuopt:cuopt:26.10.0-SNAPSHOT build 26.10.0-20260928.164422-1 to the Sonatype snapshot repo — verified independently by fetching maven-metadata.xml from the live repo afterward. The temporary pr.yaml wiring used to exercise this has since been reverted; the durable change is only in build.yaml + assemble_maven_repo.sh.
Per review request on NVIDIA#1970: replicates the artifact-gather job (runs for real) and the publish job (if: false, so GitHub Actions validates the reusable-workflow call shape without ever being able to execute a push) so this PR's own CI run exercises the new wiring.

Remove both temporary jobs before merge.
After validation, remove java-static-gather-tmp and java-maven-publish-tmp. The gather job otherwise adds an artifact upload to qualifying PR runs, while the publish job remains permanently skipped. The PR objective also identifies this change as temporary.

No publish credentials (GPG_PRIVATE_KEY/GPG_PASSPHRASE/MAVEN_DEPLOY_TOKEN/ MAVEN_DEPLOY_USERNAME) exist on this repo yet, so this can only fail cleanly at the reusable workflow's own credential check -- it cannot actually publish. Confirmed via gh api before making this change.

Keep the expected publication failure out of pr-builder.
When a Java build succeeds, java-maven-publish-tmp runs without the credentials that the PR description says are absent. The new dependency makes pr-builder fail too: its reusable workflow treats a failed dependency as an error. Remove java-maven-publish-tmp from pr-builder.needs while the publication call is diagnostic. (raw.githubusercontent.com)

Restore the PR build and test conditions before merge.
These if: false conditions skip the C++, Python, wheel, docs, and Java validation jobs for every PR. The skipped Java test job cannot validate the artifacts used by the new Maven publication path. GitHub reports skipped jobs as successful even when they are required checks. Restore the applicable changed-file conditions before merging.

mvn deploy-file (rapidsai/shared-workflows/ci/maven-publish) requires one unclassified "main" artifact at <artifactId>-<version>.jar, with everything else attached as a classifier. cuOpt has no CUDA-version- agnostic build, so there's nothing distinct to put there -- copy the cuda13 classifier jar to that name instead, matching cudf's java/ci/assemble_maven_repo.sh (which does the same from cuda12). Consumers depending on com.nvidia.cuopt:cuopt without a <classifier> get the cuda13 build. Verified locally against the real classifier JARs from PR NVIDIA#1970's CI run: the assembled cuopt-26.10.0-SNAPSHOT.jar is byte-identical to cuopt-26.10.0-SNAPSHOT-cuda13.jar.

I don't think this if condition is needed.

Removed. Credentials are provisioned now, and the only effect of this guard when they're unset is a false-positive job failure -- nothing else needs: this job, so no other job is blocked or fails. The real cost was noise: a red overall run status and a false-positive Slack alert from build-summary (which enumerates every job in the run, not just its own needs:), not worth keeping.

This should be rapidsai/shared-workflows/.github/workflows/maven-publish.yaml@main.
There was a problem hiding this comment.
This is intentional, not an oversight -- CodeRabbit flagged (CWE-829) that this reusable workflow forwards our GPG/Maven deploy secrets, so an unpinned @main ref would let anyone who compromises rapidsai/shared-workflows swap in a workflow that exfiltrates them before a run. Pinning to a reviewed SHA closes that. Given that tradeoff, I'd rather keep it pinned unless you see a reason the risk doesn't apply here -- let me know if you still want it switched back and I'll make the change.
There was a problem hiding this comment.
One more concrete reason to keep it pinned, beyond the security tradeoff: I checked release/26.10 (the branch every other rapidsai/shared-workflows call in this file uses) and its maven-publish.yaml is an older, more limited version -- it only supports publication-type: "rc" (release candidates to Maven Central) and has no Sonatype snapshot path at all (its own comment says "TODO: add nightly -> Sonatype snapshots"). The snapshot-publish capability we actually used and validated end-to-end this session -- the thing that published com.nvidia.cuopt:cuopt:26.10.0-SNAPSHOT for real -- only exists on main, at the commit we're pinned to. Switching to @release/26.10 would break the job: no snapshot path, and it'd require a publication-type input that doesn't fit our nightly/branch-push use case. So the SHA pin isn't just about the secret-forwarding risk -- it's currently the only way to get the feature this PR depends on.

In the current main branch version of build.yaml (https://github.com/NVIDIA/cuopt/blob/a5b932e4ff82798f698115b03bd435e93a6ab443/.github/workflows/build.yaml), there is a mix of @release/26.10 and @main shared workflow references, which is a bug. The main branch should reference the main branch of shared workflows, and the same should happen for the release branch. For instance, see shared workflow references in https://github.com/NVIDIA/cudf/blob/main/.github/workflows/build.yaml and https://github.com/NVIDIA/cudf/blob/release/26.10/.github/workflows/build.yaml for cuDF. The same can be seen for cuVS in https://github.com/NVIDIA/cuvs/blob/main/.github/workflows/build.yaml and https://github.com/NVIDIA/cuvs/blob/release/26.10/.github/workflows/build.yaml

Switched to shared-workflows release/26.10, matching cudf's release/26.10 java-publish job exactly (publication-type: rc, release-tag gate only, no nightly snapshots for now). Thanks for the pointer.

Is stage-for-maven-central-publish intentionally not set here?
There was a problem hiding this comment.
Set to true now. It's documented as ignored on the snapshot path (everything we've published so far) and only takes effect on an actual Maven Central release build, where it gates the first release behind a manual Sonatype Central Portal click instead of auto-publishing -- a reasonable one-time safety net for the first real release.

Why is this using the CUDA 13 classifier instead of CUDA 12?
There was a problem hiding this comment.
Deliberate: cu13 is CUDA's latest major line, so it's the forward-looking default for this new unclassified-primary coordinate. That said, the rest of cuOpt's distribution (install selector's default radio, the latest-cu12 Docker tag) still defaults to cu12 today, so this is slightly ahead of that convention rather than matching it. Open to revisiting once/if the rest of the distribution moves its own default to cu13 -- tracking as a separate follow-up rather than blocking this PR on it.
There was a problem hiding this comment.
The CUDA 12 classifier provides broader compatibility, so I think it is a reasonable default. This would also be consistent with cudf-java. Also, I think this is the right time to address this, since this PR introduces the default classifier.
There was a problem hiding this comment.
Switched to cuda12.
Credentials are provisioned now, and the guard's only effect when they aren't is a false-positive failure/Slack alert on jobs nothing else depends on -- not worth the noise. Also set stage-for-maven-central-publish so the first real Maven Central release is gated behind a manual Sonatype Central Portal click instead of auto-publishing; it's a no-op on the snapshot path we've already validated.
- showCuda's method check omitted "maven" -- the row (and the ability to pick cu12/cu13 at all) was invisible even though the classifier depends on it - Default to cu13 on entering the Maven method, matching the published jar's own unclassified-primary default (see PR NVIDIA#1970's assemble_maven_repo.sh); doesn't override an explicit pick made while still in that method
Per review: cu12 has broader compatibility, and this is the right time to set the default since this PR introduces it.
Snapshot publishing isn't wanted yet -- only need the release path working when the real tag lands. Same gate release-github already uses (startsWith(github.ref, 'refs/tags/v')). Keeps the pinned maven-publish.yaml commit as-is; it still auto-routes release builds to Maven Central via rapids-is-release-build.
Matches cudf's release/26.10 java-publish job exactly: release-tag path only, publication-type: rc, same stage-for-maven-central-publish default. Snapshot publishing comes back once cuopt main tracks shared-workflows main again.
…ng in pr.yaml Mirrors the earlier java-maven-publish-tmp approach to re-validate after switching from the pinned SHA to shared-workflows release/26.10. Disables unrelated jobs to divert CI capacity. To be reverted before merge.
Without this, the pom.xml version stays 26.10.0-SNAPSHOT even at the real release tag, and the Maven Central publish step rejects it (require_release_version) -- exactly the failure the pr.yaml test run hit. Mirrors build_cudf_java_jar_in_container.sh: rapids-is-release-build gates an mvn versions:set rewrite, restored via the existing cleanup trap. Non-release builds get a fail-fast check that the POM is still -SNAPSHOT. Verified locally: mvn versions:set correctly rewrites the version inside the VERSION_UPDATE_MARKER comments without disturbing them, and the sed-based reader picks up the stripped value.
