我有一个加载jruby的可执行jar。安装程序将jar和一些预打包的jar库（包括完整的jruby和一些gems）放入安装位置。
将jar安装到名称带有空格的文件夹中时，除了在Windows中以外，一切正常。当Jruby遇到其中一个jar打包的gem中的一个简单的“ require”（如果重要的话，它在statemachine gem中的“ require singleton”）时，它就会失败。
这本来不是什么大问题，但我需要从程序文件下运行jar。希望有人解决了这个问题:)

最佳答案
这可能是一个错误。您使用什么软件来创建可执行jar？什么版本的JRuby？过去我们已经处理过带空格的文件名错误，但是肯定还有其他错误。您可以在http://bugs.jruby.org处提交错误吗？谢谢。
关于java - 为什么加载jruby的可执行jar无法在名称带有空格的文件夹(例如，程序文件)下运行？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/8446868/
