Summary

We just noticed that the nexus-platform-plugin build pipeline stopped working recently.

For instance, the https://ci.jenkins.io/job/Plugins/job/nexus-platform-plugin/job/PR-268/1/ build fails due to:

14:15:00  [ERROR]     Unresolveable build extension: Plugin org.jenkins-ci.tools:maven-hpi-plugin:3.32 or one of its dependencies could not be resolved: The following artifacts could not be resolved: org.jenkins-ci.tools:maven-hpi-plugin:jar:3.32 (absent): Could not find artifact org.jenkins-ci.tools:maven-hpi-plugin:jar:3.32 in aws-proxy-incrementals (https://repo.aws.jenkins.io/incrementals/) -> [Help 2]

Nothing material has changed in the plugin code since the last successful build, which was on August 1 and relied on the same plugin and version as the one mentioned in the error message above (i.e. org.jenkins-ci.tools:maven-hpi-plugin:jar:3.32).

This issue blocks us from releasing new versions of the plugin.

Reproduction steps

See: https://ci.jenkins.io/job/Plugins/job/nexus-platform-plugin/job/PR-268/1/

I was able to reproduce the issue on a local build while using the settings.xml as ci.jenkins.io (and the proper SSH tunnel that I can use as an administrator).

This problem is related to the operations around Artifactory (ref. #3599).

cc @MarkEWaite it looks like this error is the one that blocks us from fully removing the Maven Central repository mirror from repo.jenkins-ci.org.

I was able to fix the error by adding an explicit pluginRepository pointing to https://repo.jenkins-ci.org/public + also setting the default repository to https://repo.jenkins-ci.org/public/ . The draft PR jenkinsci/nexus-platform-plugin#276 is an attempt to verify is the error is gone on ci.jenkins.io (e.g. in production, not on my laptop).

Continuing analysis...

For info, I might have a solution in #3599 (comment)

@eduard-tita on short time, you can merge my PR (or do your own with the same code, I don't mind) to fix your build problem (ref. jenkinsci/nexus-platform-plugin#276)

Thank you, @dduportal. I applied your changes and I got a green build again. You can close the draft PR.
