Hi all, I want to build logstash into a jar, and deploy this jar to my cluster. I found "warble" to be able to build jruby code into jar. I managed to get logstash.jar using warble, but when I run the jar file I got this error (bin/bundle is missing...) :

Any help ? Thanks!

$ java -jar ./hcd\_logstash.jar -f ./test1.conf  
LoadError: no such file to load -- hcd\_logstash/bin/bundle

This is not currently a supported deployment model.

Even when it is not a supported deployment model, I am wondering whether it is possible to reuse parts of logstash code in other projects.

My intention is to reuse the grok parser code (from logstash-plugins/logstash-filter-grok) in other parts of a project I need to make compatible with logstash. Is that something doable? Any pointers would be much appreciated.
