/**
* @author fcamblor
* Crappy hack because for the moment, in maven-scmprovider-gitext 1.8.1, when we checkIn file,
* checkin is originally made by passing pushUrl instead of a local reference (such as "origin")
* Problem is passing pushUrl doesn't update current local reference once pushed => after push,
* origin/<targetBranch> will not be updated to latest commit => on next push, there will be an
* error saying some pull is needed.
* This workaround could be betterly handled when something like "checkinAndFetch" could be
* implemented generically in maven-scm-api
* (see http://maven.40175.n5.nabble.com/SCM-GitExe-no-fetch-after-push-td5745064.html)
