导读：我在config / application.rb中添加了一些外部jar到我的CLASSPATH中： require 'java'$CLASSPATH "#{File.dirname(__FILE__)}/../backend/src/"Dir["#{File.dirname(__FILE__)}/../backend/lib/*.jar"].each do |jar| require jarend 使用rails服务器运行Rai

我在config / application.rb中添加了一些外部jar到我的CLASSPATH中：
require 'java'
$CLASSPATH << "#{File.dirname(__FILE__)}/../backend/src/"
Dir["#{File.dirname(__FILE__)}/../backend/lib/*.jar"].each do |jar|
require jar
end
使用rails服务器运行Rails时,这很好用.来自CLASSPATH的jar文件已加载.但是,在运行rake时,未设置类路径.我怎么设置它？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中已经拥有clojure.jar. (哦,我也尝试将代码放在environment.rb中;没有帮助) 通过“不工作”,我的意思是： $rake rspec --trace rake aborted!

发生这种情况是因为我使用的gem使用了import而不是java_import,命中了

JRuby: import vs include vs java_import vs include_class.
