I don't see any attachments with the mail. Anyways, you need to: 1. remove all your changes from conf/nutch-default.xml. Make it in sync with svn. (rm conf/nutch-default.xml && svn up conf/nutch-default.xml) 2. In conf/nutch-site.xml, remove the entry for "plugin.folders" 3. run "ant clean runtime"
