 Description  « Hide
When trying to checkout a Mercurial repository, QuickBuilld threw an exception indicating an "unknown revision". I have only seen this once, as the previous and all subsequent runs performed without an issue. The output is given below:

This seems not a QuickBuild bug. Please run the same command from your console on the same node:
hg -y log -l1 --template={date|rfc3339date} -r c311191f8c0dbd2ca34daf3429471c41e6966fed

here, revision c311191f8c0dbd2ca34daf3429471c41e6966fed is the version built for your previous build. Are there any merge/rebase operations occurred which cause hg drop this revision?

There were no merge operations at the point of this failure. I doubt there were any merge operations at the time. I am unable to try executing that command at the moment, but I will look into it.

When running the command again, I get the same output: "abort: unknown revision 'c311191f8c0dbd2ca34daf3429471c41e6966fed'!".

It sounds like revision 'c311191f8c0dbd2ca34daf3429471c41e6966fed'!" was dropped in your hg repository to me. I don't know why this happens, but if you can build successfully with this revision 'c311191f8c0dbd2ca34daf3429471c41e6966fed' (previous build of this error), there must be something happened in your hg repository which cause this revision disappeared.

Please consult your mercurial admin to see why revision 'c311191f8c0dbd2ca34daf3429471c41e6966fed' is not there.
