Update project configuration is not enough to update eclipse settings - need to delete .project/.classpath and reimport ----------------------------------------------------------------------------------------------------------------------- Key: JBIDE-18097 URL: https://issues.jboss.org/browse/JBIDE-18097 Project: Tools (JBoss Tools) Issue Type: Bug Components: maven Reporter: Max Rydahl Andersen Assignee: Fred Bricon Fix For: 4.5.0.AM1 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 ?
