error: value centroid is not a member of com.esri.core.geometry.Polygon

Iniziare con gli imports della Spark shell per com.esri.core.geometry.Polygon e la chiamata a OperatorImportFromWkt.local().execute mostrata nel report. Verificare l’API Polygon e il tipo dedotto di poly, quindi confrontare il punto di ingresso documentato per centroid o un test pertinente; il lavoro è completato quando si è identificato se si tratta di un problema dell’API o di utilizzo di Scala e si è documentata la chiamata supportata.

Hi i am trying to use your library in spark shell environement but i have this error message:

:36: error: value centroid is not a member of com.esri.core.geometry.Polygon

My code :

spark-shell --master yarn --packages com.esri.geometry:esri-geometry-api:2.1.0

**import com.esri.core.geometry.Geometry
import com.esri.core.geometry.Polygon

val poly = OperatorImportFromWkt.local().execute(2,Geometry.Type.Polygon,polygone,null)**

// this last execution produce my error

poly.centroid

// do you think that librairy is not compatible with scala ?
// thank you for help
