Dear team

I^m trying to build the LanKey source in IJ and get th following error:

Information:Using javac 1.8.0_91 to compile java sources
Information:java: Errors occurred while compiling module 'Dataintegration'
Information:28.04.2016 10:45 - Compilation completed with 6 errors and 0 warnings in 4s 977ms

Error:(39, 20) java: cannot find symbol

  location: class org.labkey.di.filters.FilterStrategyFactoryImpl

This two import statements are undefined:
import org.labkey.etl.xml.DeletedRowsSourceObjectType;
import org.labkey.etl.xml.FilterType;

Can you tell me where the org.labkey.etl package can be found?

Thanks for your support.
