• Missing projects - Sometimes developers add or remove project dependencies. These show up with error message "The project cannot be built until build path errors are resolved". This is often a sign that your Eclipse workspace is out of sync with your local repository or the svn repository. The full remedy is to refresh your local repos (svn update), rebuild your local repos (mvn clean install -U), regenerate Eclipse projects (mvn -Declipse), reimport projects in Eclipse, and clean/rebuild your projects. You may be able to do less than this full refresh with simple changes, but the full refresh is often needed for major changes.
