I'm trying to write a plugin for logstash. My plugin uses a library that require ruby 2+ to run. After searching around, i found that JRuby 1.7 can support Ruby 2.x. How can i force logstash jruby to use ruby 2.0.  
Thanks everyone.

Have you tried simply requiring the module?

```auto
require "module"

```

And seeing what happens?

Yes , i did. As reported here  
[https://github.com/dasch/avro\_turf/issues/61](https://github.com/dasch/avro_turf/issues/61) . I also did some research here and suspect that because ruby 1.9 does not support named arguments.  
I also see that Logstash is having a plan to move to JRuby 9k which due in logstash 5.4. I will switch to that later.Now, I just need some way to force JRuby to use RUby 2.0 which is probably possible here: [http://stackoverflow.com/questions/15281036/how-to-run-ruby-2-0-with-jruby-1-7](http://stackoverflow.com/questions/15281036/how-to-run-ruby-2-0-with-jruby-1-7).  
However, Logstash complain when i try to do that.  
Thanks you
