 Description   
Sometimes, more or less often, git fetch command executed by quickbuild fails with the following error message/response:

> 2018-07-12 09:43:48 - Failed to run command: git fetch --all --tags -q
> Command return code: 1
> Command error output: fatal: git fetch-pack: expected ACK/NAK, got 'A ref was requested that is no longer valid. The ref may have been updated while the git-upload-pack request was received. Please try again.'
> fatal: The remote end hung up unexpectedly
> error: Could not fetch origin

This is caused by the nature of the http(s) request used by git and modifications during these, which occurs more likely with increased action on a repository.

Quickbuild should follow the advice in the response and retry the fetch command automatically to avoid failures during CHECK_BUILD_CONDITION.

Basically this would make sense for every git command. If there is a "Please try again" contained in the message it really should try the command again.

We plan to get this into next big version of QB planned to be released in the end of this year.
