问题
The project I'm doing is written in Java and parsers source code files. (Java src up to now). Now I'd like to enable parsing Ruby code as well. Therefore I am looking for a parser in Java that parses Ruby source code.
The only thing I have been able to find up to now are Ruby parsers in Ruby (ParseTree and RubyParser...). I could maybe parse the source files I want with a Ruby parser in JRuby, and then access my Java stuff from there. But that would mean that I will not be able to reuse a lot of my previously written Java code.
Is there a decent Ruby parser in Java out there and have I just not be able to find it? Or does someone see a better solution?

See http://kenai.com/projects/jruby-parser/

You could let ANTLR generate a lexer/parser for you. They have a simplified Ruby grammar available: http://www.antlr.org/grammar/1160820213459/rubyParserLexerSPGrammar.g which may be sufficient for your needs.
