Eclipse RCP product export: Cannot satisfy slf4j dependency - eclipse-rcp

Question

I am building existing RCP application against this target platform:
The PDE build worked fine just few weeks ago and then something happened, presumably Eclipse updated itself? or something like this.. Now I am getting this dependency error which makes no sense because by the look of it the required plugin and exported package is present in the target platform. If I disable p2 "Generate p2 repository" in the export dialog, the build works fine.
Property "p2.director.log" has not been set
