We use hierarchies of builds, and some builds can be used both standalone and as parts of larger pipeline (ex workflow) builds.

We use CopyArtifact plugin to copy artifacts from child builds into pipeline build, however it doesn't work with HTML pages that are created by PublishHTML report.

Workaround is to use both PublishHTML and ArchiveArtifacts steps, however that stored HTML pages twice (and they can be quite large).
