> Based on a discussion on the users list [1], Maven 3 has changed how it resolves artifacts
from remote repositories.  Unfortunately, when "conflicts" arise ( GAV is cached in local
repo, but POM has no matching repository id declared ), Maven just tells the user that the
artifact could not be resolved.
> This leads to confusion from users who find the .jar files in their local repository,
and they just get frustrated and complain that "maven sucks".
> It would be good if Maven was updated with some improved error messages along the lines
of:
> "The {GAV} artifact was found in your local repository, but came from the undeclared
repository "xxx", either configure this in your pom with {insert sample XML block in error
message}, or in your "yyy" mirror."
> The "mirror" section of the error message should be included -if- the current ~/.m2/settings.xml
declares a mirror.  By improving the messages here we can help the users move on to building
software, rather than pulling out their hair :)
