Artifact Dependencies

Hi,
I have a build which produces a series of artifacts that look like this:

• folder
  • with.extension
  • withoutextension
• folder.1
  • with.extension
  • withoutextension

Another build depends on these artefacts using **/* as the artifact path.

The files that get download to the agent look like this:

• folder
  • with.extension
  • withoutextension
• folder.1
  • with.extension

Note that folder.1 is missing the file withoutextension.

It appears that any files that do not contain a period in a folder that does contain a period are not downloaded.

What am I doing wrong here? What is the correct artifact path to use in this case?
I have tried this on 4.5.5 and 5.1.3 with the same result.

Thanks,
Derek
