Hi!
Don’t worry about the late response.
About the source for the jar file, I got it from WEKA webpage/forum. I’m using a specific tool of Weka and I downloaded this jar file from the application (it has an integrated component downloader). On the other hand, the maven coordinates to integrate it, I’m not really familiar with it, so I’m not sure what is it that I need to find, anyways I google it and I got this page:
https://mvnrepository.com/artifact/nz.ac.waikato.cms.weka/timeseriesForecasting/1.1.27
I didn’t know about the issue of the licences. I will now read about it and inform you of any news.
Best regards,
Carlos
