I tried wiping out the workspace and that didn't change anything.

I found the source code that produces this message, but don't know how I get into this state to try to fix it

Ugh. This shouldn't happen…

Could you provide the wrapper HTML file archived in Jenkins next to the HTML report, as well as the build.xml file?

The job's config.xml can't hurt either.

What happens starting in HTML Publisher 1.10 is that the generated HTML Publisher wrapper file gets its checksum recorded during creation, and that checksum is stored in the build.xml.

Before serving the file afterwards, if the checksum in the build.xml is present (for backward compatibility), it gets recalculated from the archived file. If there's a mismatch, the file isn't served.

Is the wrapper file something I'd get off the filesystem of the Jenkins server (and not through the web interface)?

I'm uncomfortable uploading the entire build or config file (there's some sensitive URLs, etc in these files), so let me snip the relevant parts. Let me know if you need more.

build.xml

          <allowMissing>true</allowMissing>
        </htmlpublisher.HtmlPublisherTarget>
      </reportTargets>
    </htmlpublisher.HtmlPublisher>

I am also seeing this issue after I have updated to Jenkins 1.645 and updating HTML Publisher Plugin from 1.06 to 1.10. Please let me know if more details are needed.

Are all of you on Windows (Jenkins master)?

I'm running the master on CentOS 6

Please provide the output of the following script when run in Manage Jenkins » Script Console:

java.nio.charset.Charset.defaultCharset()

Have the same issue.

Master is on Ubuntu 15.04

And the script output is:
UTF-8

UTF-8

windows-1252

I also have the problem that I usually get the "Checksum mismatch" error. (Jenkins and all plugins are up-to-date.)
I hope I can shed some light on the problem. There are certain conditions I have noticed.

• The problem does not occur when there is a single HTML report.
• The problem does not occur for the first HTML report.
• The incorrect checksum is reported, an example:
  "The checksum of the current wrapper file (checksum from 2nd report) does not match the recorded checksum (checksum from 1st report)."
• Sometimes no error is reported, so it may not be deterministic.
• The problem does not occur if you select the job and open the report from left column.
  Checksum error -> http://.../job/JOB-NAME/HTML-NAME
  No checksum error -> http://.../job/JOB-NAME/JOB-ID/HTML-NAME

jonw Thanks for the detailed analysis! It helps a lot. I'll see what I can do. I'll be traveling next week, so I hope to get this done this week. No promises though.

jonw (and everyone else watching): Proposed fix at https://github.com/jenkinsci/htmlpublisher-plugin/pull/23

Please take a look, maybe give the PR build https://jenkins.ci.cloudbees.com/job/plugins/job/htmlpublisher-plugin/61/ a try?

Thanks for the quick fix. I only tested it superficially, but it looks good.

I also tested it briefly, looks OK for me as well.

> Note: I cannot reproduce the error if I only create 2 reports, I also must mark the publishing option: 'Keep past HTML reports'

This was my experience as well but I was unsure about it and not sure if it was relevant.

Yep, it's important, otherwise a different branch in the code is taken. So you need a) multiple reports per build, b) archiving reports of past builds, c) access reports through project-level links. Therefore the instructions how to reproduce the issue were essential.

(This is really a bit of a hack because if you archive reports for past build, it switches to a different mode in which reports are attached to builds rather than to the project, and the project-level links essentially forward to the build-level archive… and that's where I messed up the checksum change for 1.10 – but it's only apparent when you archive multiple different reports.)

Compare: https://github.com/jenkinsci/htmlpublisher-plugin/compare/4a8d86addf84...9dd6fe1ea02d

Released as HTML Publisher 1.11, let us know how it works for you

I converted all of my custom reports to plugin-based-reports! If no one else can repro the fix, I'll try to spin up one of my older configurations.
