PR check failing - why?

[Fritz Elfert]

Hi,

can someone please enlighten me. What is the check labelled
"continuous-integration/jenkins/pr-head" in a PR supposed to check and
why is this one failing:

https://ci.jenkins.io/blue/organizations/jenkins/Core%2Fjenkins/detail/PR-2639/1/

Perhaps some core dev can shorten the description of that check. It
tries to tell me something in the GUI but the text is cut off. It reads:

continuous-integration/jenkins/pr-head — This com...

Thanks
-Fritz

It builds the head commit of the PR branch (rather than merge it into the base branch, then build that).

It is likely failing due to a regression in a plugin update yesterday:
https://ci.jenkins.io/blue/rest/organizations/jenkins/pipelines/Core/jenkins/branches/PR-2639/runs/1/log/?start=0

I filed https://issues.jenkins-ci.org/browse/INFRA-981

Bug in GitHub more than anything else. I'd have expected there to be a complete text in the tooltip, but there is no tooltip.

Seems like the blue ocean is cutting off parts of the build log, the full log is here

https://ci.jenkins.io/job/Core/job/jenkins/view/Pull%20Requests/job/PR-2639/1/console

hudson.plugins.git.GitException: org.eclipse.jgit.errors.MissingObjectException: Missing commit 6aac6e3159b4108114591f610d4a9508506d5016

Maybe an intermittent GitHub error?

I've seen this on every first (#1) PR build in the last day or so, since rtyler upgraded plugins.

E.g.
https://ci.jenkins.io/blue/organizations/jenkins/Core%2Fremoting/detail/jtnord-patch-1/1/pipeline/
https://ci.jenkins.io/blue/organizations/jenkins/Core%2Fjenkins/detail/PR-2638/1/pipeline/
https://ci.jenkins.io/blue/organizations/jenkins/Core%2Fjenkins/detail/PR-2639/1/pipeline/

Plus a number of others that have already been merged and therefore vanished.
