Hey,

our Unity build on CI just failed with the following output:

Build succeeded
BuildPlayer "succeeded" with 1 error(s). Assuming success. 

Processing asset pack 1 of 14...
IOException: Error 183 
(Filename: <fb001e01371b4adca20013e0ac763896> Line: 0)

The MSDN docs say the following about this error:

ERROR_ALREADY_EXISTS

183 (0xB7)

Cannot create a file when that file already exists.

My guess is that the temp path returned by GetTempFolder in AppBundlePublisher might clash, and we might have had 2 builds running at the same time on the same machine.

I tried calling that method now on my machine several times and it always returns the same path in OSX.

Any chance you could change that by adding some uniqueness to the path?
