DSC Archive Resource (unzip) holds zip-file
This is more a indirect failure experience. Please bear with me if this is the wrong place: Expanding a zip-file with DSC in an Archive Resource leaves a process holding the zip-file. This gives that the zip-file can not be deleted by the same script or in the same PowerShell session.
The error message from Remove-Item on the zip-file is like this: "Remove-Item : Cannot remove item C:\temp\jjdk1.8.0112-CE.zip: The process cannot access the file 'jdk1.8.0112-CE.zip' because it is being used by another process.".
In issue 240 to Plaster on GitHub (https://github.com/PowerShell/Plaster/issues/240) it is mentioned by Keith Hill (rkeithhill) that Get-FileHash leaves a handle on the file. This I refer to as the DSC Archive Resource has validation options on checksum.
