You have a network share mapped as a drive and you want your TeamCity Agent to copy files to it when it’s done building. But it doesn’t work. Your users are fine (run “whoami” in TeamCity script and look at the output to make sure).
In the TeamCity build logs you’ll see something like this:
ERROR 3 (0x00000003) Getting File System Type of Destination
The annoying part is that it works just fine when you run it via the command prompt.
In short, the issue is likely that when Robocopy doesn’t use the interactive user session, so even if you’re logged in with the user under which the TeamCityAgent service is running, and you have the network drive mapped just fine, Robocopy won’t be able to see it. So, you could put a “net use” command just before your robocopy command, but then you’ll have to remove it again afterwards, which would be prone to failure… though maybe remove-then-add just before? Anyways, just point it directly at the network share for your robocopy command. That way, you only have to make sure your TeamCityAgent user has permissions on the network share.
