Repository to build xgboost4j for Linux/MacOSX using TravisCI.
When pushing a tag to git, TravisCI automatically creates a release.
This project publishes xgboost4j to Maven central that contains portable binaries for MacOSX and Linux. DMLC's xgboost is a great library but, as seen in this issue, it is not published to maven central yet.
