我加入这config/application.rb添加了一些外部罐到我的CLASSPATH：如何正确添加到JRuby on Rails项目中的CLASSPATH？
require 'java'
$CLASSPATH << "#{File.dirname(__FILE__)}/../backend/src/"
Dir["#{File.dirname(__FILE__)}/../backend/lib/*.jar"].each do |jar|
require jar
end
此使用rails server的运转轨道时工作正常。加载CLASSPATH中的罐子。但是，在运行rake时，未设置类路径。我该如何设置它？特别是，我需要在加载我的宝石之前设置它，因为我使用JRClj gem，它依赖于我的CLASSPATH中已经有clojure.jar。
（呵呵，我也试图把在environment.rb中的代码;没有帮助）
通过“不行”，我的意思是：
$ rake rspec --trace
rake aborted!
