There are two CI/CD processes for OpenNLP.

Jenkins

The Jenkins job builds the OpenNLP artifacts and publishes the snapshot dependencies to Maven Central. 

Buildbot

The Buildbot job publishes website changes. The job monitors the opennlp-site repository for changes. When changes are found, Buildbot builds the site and pushes it to the asf-site branch. The OpenNLP website will then be updated to the newest revision.
