Metacello implementation of the github protocol uses a zip file downloaded from github and then extracted in a temp folder. See https://github.com/dalehenrich/metacello-work/blob/master/repository/Metacello-Platform.pharo30.package/MetacelloPharo30Platform.class/instance/downloadFile.to..stMetacello code is not robust enough. It should check for a not-used temporary file name. Check MCGitHubRepository>>projectDirectoryFrom: version:
zipFileName := '/tmp/github-'
, (downloadCacheKey select: [ :c | c isAlphaNumeric ]) , '.zip'.
The problem is not related to Zinc.
So, Metacello should be fixed. As a workaround, you can also specify to run only 1 instance of your job at a time.

Looks like ZnFileSystemUtils are doing this. As far as i understand, the problem occurs when two matrix lobs run at the same time and so one downloads thing into /tmp, and other one encounters a problem. Isn�t this some sort of bug in Zinc?

Sorry for bothering guys, but I really get random errors. For example last one I saw is:
An attempt to use interactive tools detected, while in non-interactive mode
FileDoesNotExistException: '/tmp/github-UkoVnaExportermaster.zip'
Can anybody help me to localise the problem? Is the Jenkins configuration wrong? Or I should do things in a completely different way?
Did you specigy /tmp as output folder? If so, you should use the working directory (which will be the build directory). You can not assume to have write permissions on /tmp.
Yes, that�s the thing. I guess /tmp is used by something in metacello-filetree-github toolchain. That�s why I�m asking because I�ve never worked with is a lot.

Hi guys,
So I�m using this fancy metacello github urls, like: github://<user>/<project>[:<branch>|<tag>|<SHA>][/<path>] and some of my Jenkins matrix builds are randomly failing with:
Error: /tmp/github-UkoRenrakumaster.zip already exists
anyone has an idea how to solve this?
