update

sorry haven't gotten around in long. tried deleting solr/ directory , restarting. able run bundle exec rake sunspot:solr:start , bundle exec rake db:seed without problems, still have error when try:

bundle exec rake sunspot:solr:reindex 

i see following stacktrace

$ bundle exec rake sunspot:solr:reindex rake aborted! undefined method `includes' event:class /home/my_username/.rvm/gems/ruby-1.9.3-p429/gems/mongo_mapper-0.12.0/lib/mongo_mapper/plugins/dynamic_querying.rb:39:in `method_missing' /home/my_username/.rvm/gems/ruby-1.9.3-p429/gems/sunspot_rails-2.1.0/lib/sunspot/rails/searchable.rb:254:in `solr_index' /home/my_username/.rvm/gems/ruby-1.9.3-p429/gems/sunspot_rails-2.1.0/lib/sunspot/rails/searchable.rb:203:in `solr_reindex' /home/my_username/.rvm/gems/ruby-1.9.3-p429/bundler/gems/sunspot_mongo_mapper-b6cf3edca97a/lib/sunspot/mongo_mapper/tasks.rb:21:in `block (3 levels) in <top (required)>' /home/my_username/.rvm/gems/ruby-1.9.3-p429/bundler/gems/sunspot_mongo_mapper-b6cf3edca97a/lib/sunspot/mongo_mapper/tasks.rb:20:in `each' /home/my_username/.rvm/gems/ruby-1.9.3-p429/bundler/gems/sunspot_mongo_mapper-b6cf3edca97a/lib/sunspot/mongo_mapper/tasks.rb:20:in `block (2 levels) in <top (required)>' /home/my_username/.rvm/gems/ruby-1.9.3-p429/bin/ruby_noexec_wrapper:14:in `eval' /home/my_username.rvm/gems/ruby-1.9.3-p429/bin/ruby_noexec_wrapper:14:in `<main>' tasks: top => sunspot:solr:reindex => sunspot:reindex (see full trace running task --trace) 

so know problem is?

any insight issue appreciated! thanks!

i had same error triggered bundle exec rake sunspot:solr:reindex, helped force quitting java processes find. after restarted solr with

bundle exec rake sunspot:solr:start

i reindex without errors.
