I get the following two errors reported by Eclipse when I import the official 4.0 GA download version of the drools-examples-drl project:

1. Unable to find unambiguously defined class 'Customer', candidates are: [org.drools.examples.Customer, org.drools.examples.TroubleTicketExample$Customer] drools-examples-drl/src/main/rules/org/drools/examples in TroubleTicket.drl

2. Unable to find unambiguously defined class 'Customer', candidates are: [org.drools.examples.TroubleTicketExampleWithDSL$Customer, org.drools.examples.Customer] drools-examples-drl/src/main/rules/org/drools/examples in TroubleTicketWithDSL.drl

Is this a bug in 4.0GA , or is there further configuration required after importing the examples project? I'm using the 4.0GA release version of the drools Eclipse plug-in.

I also noticed that I don't get this error from the latest version of drools in the trunk (i.e. including post 4.0GA changes), so maybe this has already been fixed since release 4.0GA?

Exception in thread "main" java.lang.Error: Unable to find unambiguously defined class 'Customer', candidates are: [org.drools.examples.TroubleTicketExample$Customer, org.drools.examples.Customer]
