Review details

Suppressed comments (1)

ci/build_docs.sh:72

• The generated files are staged under cudf-java, but both publish-api-docs callers still pass only cudf,dask-cudf,libcudf (.github/workflows/pr.yaml:488 and .github/workflows/build.yaml:178). The shared publisher uses that input as its project matrix, so these Java docs can be uploaded by rapids-upload-docs but are never downloaded or published. Add cudf-java to both workflow inputs as part of this change.

mkdir -p "${RAPIDS_DOCS_DIR}/cudf-java/html"
mv target/site/apidocs/* "${RAPIDS_DOCS_DIR}/cudf-java/html"

📝 Summary

Summary by CodeRabbit

• Documentation
  • Added cuDF Java API reference documentation to the published documentation output.
  • Updated documentation build requirements to support Java API documentation generation.
  • Documentation builds now run when Java configuration or source files change.
  • Documentation publishing is skipped when an earlier documentation build step fails.

Walkthrough

The documentation workflow adds Java build tools, detects Java source changes, and prevents documentation upload when Java documentation generation fails.

Changes

Java API documentation

Layer / File(s)	Summary
Configure Java documentation inputs dependencies.yaml, conda/environments/*, .github/workflows/pr.yaml	Documentation environments add Maven and OpenJDK 17. The build_docs file group includes Java Maven and source paths.
Validate documentation generation before upload ci/build_docs.sh	Java documentation generation runs before fail-fast handling is disabled. The script checks EXITCODE and skips upload after a generation failure.

Include java/.mvn/** in build_docs. ci/build_docs.sh runs Maven from java, so java/.mvn/maven.config affects published cudf-java API documentation. A change only to this file can skip docs-build and its dependent publish-api-docs job, leaving the published documentation stale.
