Recently we started using spotless in openHAB (http://github.com/openhab/openhab-addons). We are currently not able to do a full build (around 260 sub-projects) with checks enabled due to resource issues. It seems that this does not depend on the OS as it shows on our Unix-based CI and also on local builds under Windows. - [3.6.1] maven version - [1.30.0] spotless version - [4.13.0] eclipse version A first analysis can be found here: https://github.com/openhab/openhab-addons/blob/2.5.x/pom.xml
