Thank you very much for reviving this project. It was strange to have so many components that depend on a module that was archived.

Please consider to expand the method DefaultBuildContext.addMessage(...) to also log info messages. Currently only ERROR and WARNING are printed. This would mean adding a new constant SEVERITY_INFO to the interface BuildContext and extending the switch statement in the addMessage(...) implementation. Maybe also a default branch would be useful.

Note that adding a INFO message (severity == 0) inside Eclipse works and adds a INFO IMarker to the file (tested with 2021-12).
