If we were to be pedantic here, Austria was losing badly against Serbia for more then a year. At that time it was clear that Austria did not have a standing chance to win against Serbia in any meaningful way without extensive help from other countries, so the conflict couldn't really be qualified as minor. The things started to change when German army joined with Austrian forces in attack to Serbia, and Bulgaria decided to step in and stab Serbia from behind, but at this point the conflict was already far from "minor" and "local".
