I think I have a conflict involving different libraries using different versions of JodaTime. I have no idea how to fix this.
I have nearly the same problem as this: http://stackoverflow.com/questions/21487476/maven-build-throws-jodatime-exception-at-runtime However, in my case, I'm building a web app in Clojure, whereas my co-worker is building our Natural Language Processing engine in Java. The NLP is included as a jar. We had this working for a few weeks, but my co-worker has added some new dependencies that are now giving us this error. This person also reports a similar error: Error creating edu.stanford.nlp.time.TimeExpressionExtractorImpl See here: http://mail.wso2.org/mailarchive/dev/2014-September/035337.html with an answer here: http://mail.wso2.org/mailarchive/dev/2014-September/035341.html The issue in both cases seems to be a version conflict in different libraries, but I have no idea how to resolve this. In the Clojure app we use clj-time, which apparently uses Joda-Time 2.6, whereas the Stanford Core NLP libraries seem to use Joda 2.1. Is there anyway to resolve that conflict? Both pieces of software compile, and the Clojure app can start, with the NLP engine included. However, the Clojure app then calls a "start" method in the NLP engine, which causes the NLP engine to load the lexers and parsers that it needs. We then get these messages and errors: Loading classifier from /home/safflower/apricots/dependencies/english.muc.7class.caseless.distsim.crf.ser.gz ... done [1.5 sec].
