"No coverage information found on head" on Github, and no PR comment


Code coverage reports are being uploaded correctly to codecove, the website shows what seems to be correct data/reports, BUT the github status check state “No coverage information found on head” and the PR comment isn’t being added.

What is most bizarre is that doing identical changes to a fork of the project performs as-expected, with PR comments being added promptly etc.

As suggested elsewhere, I have removed the codecov app and then re-added it but this has been without success.

Expected Results

Github status checks to report coverage, and a PR comment to be posted.

Here is a working example from an arbitrarily “old” PR (about two weeks ago):

Actual Results

No PR comment being added. At the time of writing this, PR 3208 (linked to below) status checks completed over five hours ago and I can see all uploads in the “build” tab – screenshots included within the PR.

“No coverage information on head” on the status check


Additional Information

Context: The JavaParser project has two parts – “core” and “symbol solver”.

It was noted recently that code coverage for the symbol solver section isn’t being reported – investigating this, it seems that it is a surefire error on our part (argline being overwritten).

Fixing this introduces a new problem of the PR comments not being shown, and the status checks reporting “No coverage information found on head”.

I am now (reasonably) confident that coverage reports are being produced correctly but the

@MysterAitch there seems to be a lot of things going on here, so apologies if I miss something. What I noticed is that for this PR, you didn’t get a comment because there were not enough builds and when there were enough, the PR was already closed/merged.

@tom – Cheers for looking into it!

I’m not entirely sure your description matches what happened. To confirm the timeline:

  • The PR was created at 13:34
  • At 14:05 there were 54 (of 54) uploads (per the screenshot) and no comment
  • At 19:03 there was still no comment, and I merged it.

When during this should the comment have been added? And at what point after the merging of the PR did additional reports come in?


To follow up on this, I see that codecov still shows 54 uploads.

If it’s a problem with processing the uploads, note that I was running similar PRs on a branch to try and test things out – comments there were being added within minutes.

@MysterAitch, I’m sorry this one got away from me a bit. I wanted to check back and see if we had fixed this from improvements in our infrastructure.
