Subject Re: predictionIO classpath
Date Wed, 05 Oct 2016 08:17:11 GMT
Hi guys,
thank for the quick replies,

I tried to modify the code in the Recommendation Engine Template (that has
the "io.prediction" classpath) to follow the section "Customizing Data
Preparator" in the quickstart tutorial.
Here the classpath is "org.apache.predictionio". I changed  the classpath
in build.sbt and in the scala file, but when I make the build phase the
result is;

It seems that the "org.apache.predictionio" dependencies cannot be
resolved, while the other ones can.
Did I do something wrong?

Many thanks,
