Guided Score Card can't works in 7.9.0.Final and 7.10.0.Final

Please check the unit test which is ignored at https://github.com/kiegroup/drools/blob/8af7475e4d8c3ba09af91592196b0744ed321346/drools-scorecards/src/test/java/org/drools/scorecards/ExternalObjectModelTest.java#L60 Similar errors when compiling from scorecard source. Is this still WIP or a regression of https://github.com/kiegroup/drools/pull/1922 ?
