Whenever a new Jenkins Infrastructure CI build of pull-requests of either of the following is run:
- an up-to-date fork of the Jenkins main repository (https://github.com/jenkinsci/jenkins)
- an incrementalified Plugin under the jenkinsci repository
An incremental build version and artifact fails to generate. This is observed as an "Internal Server Error" during the "deploy" phase of the CI build.
Examples of this CI build-'server error' observed are found in the attached 'Server Error Example' links.
In the linked examples of pull requests to Jenkins-core, at the time of starting those CI builds, their branches were up-to-date with the Jenkins base branch. Yet an incremental version (and its artifacts) of Jenkins still failed to be generated by the Azure incremental-deployment/publisher server.
