This problem happens when the morphia module is being loaded from both the application.conf and dependencies.yml

To resolve it, go to your application.conf and comment out the line below "load morphia module", then restart Play. 

# load morphia module 
#module.morphia=${play.path}/modules/morphia-1.2.3d
