I'm finding this more and more worrisome so wanted to record it.
When trying to fix
JBDS-2847 or rather fix javee7-samples to be able to import easily we easily end up with a set of projects where settings are wrong.
I updated the parent pom to not have the groovy compiler enabled and ran update project configuration - and the changes regarding source paths did not take effect.
Only way to fix was to nuke all files and reimport.
can this be true ? no way to "force" an update ?
