I have used Binary Distribution to install PredictionIO 0.12.1, I have successfully started pio. After that I have used Quick Start - E-Commerce Recommendation Engine Template. At the time of building, I am getting Error that "[ERROR] [Engine$] No engine found. Your build might have failed. Aborting."

After struggling with a binary distribution, I have downloaded the source and build the binary with required dependency.
It was a permission issue. I am using Ubuntu 18.04 and I need to provide the read permission to particular template folder ( in this case MyECommerceRecommendation)
After giving permission, it was working fine.
Thanks,
