[Alex]

Is your feature request related to a problem? Please describe.
No.

Describe the solution you'd like
A spoiler in the release description for the native artifacts.

Describe alternatives you've considered
None.

Additional context
It would be handy if these artifact/group ids were readily available for those of us who bundle our natives rather than have them get fetched at runtime.

@e3ndr I included the native artifact ids in the release builder. Also the issue with input stream closing should be fixed now.
