Hi,
I am able to setup PredictionIo successfully in my MAC machine. I am also able
to start the eventserver and add events to it. But when am trying to build the
Similar-Product engine template using 'pio build --verbose', I am facing
compilation errors. Below is the trace.

Then I found someone mentioning
here<https://groups.google.com/forum/#!topic/predictionio-user/QIlYDKVB1pk>
that the package name should not contain hy-phen. So I changed from 'package
incubator-predictionio-template-similar-product' to 'package
incubator.predictionio.template.similar.product' in all classes.
After that, above errors went off but I got new compilation errors. Below is
the trace.

Do I need to change anything else or am I missing something. Please help me in
resolving these issues.
