Playframework and Spark classpath issue -

is there workaround issue? managed integrate spark in playframework in dev mode?

i'm running playframework-2.5 application uses spark-sql-2.1.0 read csv file. class should instantiated spark-sql listing2exported.

i read there might classpath issues when run in dev mode , can confirm that.

• dev mode: if execute activator run exception
• prod mode: if execute activator start file read properly.

.

case class listing2exported (     extractor:option[string],     categoryid:option[int],     categoryname:option[string],     productname:option[string],     productcode:option[int] ) 

the exception

1) error injecting constructor, scala.scalareflectionexception: class org.raisercostin.namek.io.listing2exported in javamirror playdependencyclassloader{.... ] not found.     @
