you are not using the right template code. It’s not io.prediction… anymore it’s org.apache.predicitionio… now
The templates donated to Apache linked to on the web site are not updated to the build method yet. There are PRs for many of the repos that have versions that will build fine. For instance look here for the SimilarProducts template: https://github.com/apache/incubator-predictionio-template-similar-product/pull/12 <https://github.com/apache/incubator-predictionio-template-similar-product/pull/12> hover over the PR source and you’ll see where to pull the template from. Chan Lee has ported them and they are waiting to be merged with their Apache repos. One of the committers should merge these or change the templates page to point to Chan Lee’s repos. I would do it but am a bit busy right now.
