Hello,
I would like to write a custom Logstash Input plugin in java. I realise ruby/jruby is native in this instance, but Id rather not introduce new languages to my project. What is the simplest way to do this?
It can be done, but you'll have to do a bit of JRuby as wrappers around your Java code.
A very small example of Java code inside of JRuby code is the date filter plugin.
