Ruby on rails Rails：使用'；文摘'；在jRuby 1.7.6中激活失败

使用RubyonRails3.1.14和JRuby1.7.6，我无法执行

RAILS_ENV=production RAILS_ENV=production /path/to/jruby -S rake --trace assets:precompile:all

设置以下选项时：

# config/environments/production.rb
config.assets.digest = false

它会产生以下堆栈跟踪：

** Invoke assets:precompile:all (first_time)
** Execute assets:precompile:all
** Invoke assets:precompile:primary (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)
** Execute environment
** Invoke tmp:cache:clear (first_time)
** Execute tmp:cache:clear
** Execute assets:precompile:primary
rake aborted!

问题似乎发生在以下行：

# actionpack-3.2.14/lib/sprockets/assets.rake:12
fork ? ruby(*args) : Kernel.exec(FileUtils::RUBY, *args)

我似乎很清楚，这个

exec

语句不能与jRuby一起工作。只有当

digest

设置为

true

时，才会执行此行

这是rails bug吗？在提交错误报告之前，我想在这里问一下。

为了完成这件事：它肯定与jRuby不兼容，请参阅以供参考。遗憾的是，他们不会为Rails 3修复它
