Herve Boutemy updated MNG-5185:
-------------------------------
Description:
Based on a discussion on the users list [1], [Maven 3 has changed how it
resolves artifacts from remote
repositories|https://cwiki.apache.org/MAVEN/maven-3x-compatibility-notes.html#Maven3.xCompatibilityNotes-ResolutionfromLocalRepository].
Unfortunately, when "conflicts" arise (GAV is cached in local repo retricted
to some repository ids, but actual 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
:)
