Matt Burgess commented on NIFI-210:
-----------------------------------
Needs a tweak for Groovy, currently the module path is supposed to point at a
folder containing any resources needed by the script. This folder often
contains scripts written in the same language (such as is the case with
Jython). However Groovy wants JARs, and if you specify a folder it will be
looking for classes in that folder, not JARs containing classes. So "module
path" should support a comma-separated list of paths, which can be files or
folders. This will retain the existing functionality for other languages, and
allow Groovy to add JARs to its classpath for use in scripts.

> UPDATE: The ScriptEngine for Clojure is not being maintained and is not
> currently available via Maven Central or a public repository. Recommend
> adding Clojure as a separate Improvement Jira case.
> UPDATE: Scala support proved too buggy using plain script engine. Needs
> much further analysis/review/testing before inclusion.
