我有一个rake任务，在dev env中运行正常，但不是prod。
task :sample_test_quote => :environment do
QuoterTester.test
end
QuoterTester是一个带有类方法测试的模型类。
在dev下运行任务可以正常工作，如下所示：
rake sample_test_quote
在刺激下，我得到了这个：
$ RAILS_ENV=production rake sample_test_quote --trace
** Invoke sample_test_quote (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute sample_test_quote
rake aborted!

我正在使用JRuby 1.6.5，使用mysql - prod和dev database.yml几乎是相同的设置。还使用Gemfile - 见下文。
从这个question开始，我猜测它与项目中的一个类有问题。
那么，关于如何追踪哪个班级的任何提示？
奇怪的是，rails服务器/控制台都在prod env中工作 - 我原本以为它们也会失败。
TIA，Chris

如果启用了config.threadsafe!，则在生产模式下运行Rake任务时这是一个相当常见的问题，它应该适用于JRuby应用程序。
可能的解决方法是编辑您的环境，以便仅在运行Rake任务时禁用config.threadsafe!（您可以为此目的组建自己的环境变量）。
