I approved the changes because they are good on their own merit but do not seem to be fixing the site build issues per the precommit report.

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.21.0:site (default-site) on project hbase: Execution default-site of goal org.apache.maven.plugins:maven-site-plugin:3.21.0:site failed. NullPointerException -> [Help 1]

I think more needs to be done here before we can claim it is a NPE fix @PDavid

Umeshkumar9414 · 2026-01-29T17:26:31Z

I did tried it on my local. It didn't give me NPE this time. Let me run it for multiple times.

PDavid · 2026-01-29T18:21:12Z

Hi @apurtell,

I think mvn site is now successful in this branch, see: https://ci-hbase.apache.org/job/HBase-PreCommit-GitHub-PR/job/PR-7694/1/artifact/yetus-general-check/output/patch-mvnsite-root.txt

On base branch (branch-2.6) it still fails as expected: https://ci-hbase.apache.org/job/HBase-PreCommit-GitHub-PR/job/PR-7694/1/artifact/yetus-general-check/output/branch-mvnsite-root.txt

Apache9

We should also include this for branch-2 and branch-3?

It is solving this NPE problem, Thanks @PDavid

PDavid · 2026-01-30T19:45:36Z

@Apache9 branch-2 yes, thanks. I'll open a PR soon for this. On branch-3 this src/site/xdoc/cygwin.xml does not seem to exist.

Many thanks all for reviewing this. 👍
