So it seems that changing the package names in the parser from yasp to co.yasp has, in some way, caused the tests to fail. More explicitly the one-jar process throws a ClassNotFound exception looking for co.yasp.Main.
I hope I've not got something configured somewhere?
Yep I've rebuilt. This happens at test runtime I think. (I don't have the failure in front of me atm.) I've actually got the retriever running with the changes to the parser in the code (So it must have made it's way through the build ok.
