Consider following situation: Job "A" configured to aggregate artifacts from jobs "B", "C" and "D". "B" and "D" jobs have builds, job "C" - don't.
When I run job "A" CopyArchiver plugin aggregates artifacts from job "B", then it say in output console:

[CopyArchiverPublisher] The selected has never built. No copy will be proceded.

and skips aggregating of "D"'s artifacts.

Expected behavior: CopyArchiver skips "C"'s artifacts, but aggregates artifacts from left jobs, like "D"
