This bug is filed because groovy18 in rawhide lists jline as R/BR in its spec file. Please see bug 1022897 for more info. Note that jline will become version 2.x. It would be strongly preferred if your package could be made to work with jline 2.x. If this is not possible please change the R/BR to jline1 (see bug 1022908). Thanks for your cooperation!
Feel free to close this bug once groovy18 has been updated in rawhide.
Fixed in Rawhide.
