Note: Last nightly OpenCB build passed for sbt/sbt https://github.com/VirtusLab/community-build3/actions/runs/16686887609/job/47238949362 using the main branch
It also passed locally for 3.7.2 for current main (develop branch), however, OpenCB setup might have modified some of the flags used during the compilation, eg. it might set explicitlly -source, remove -Werror, etc.
