If you're not using jom on Windows then you can stop reading here. There's a new version of jom available at https://download.qt.io/official_releases/jom/jom_1_1_6.zip Changes since jom 1.1.5 - Fixed a regression that led to inference rules not being applied if the target already had commands (QTCREATORBUG-33978).
