Jason Dillon commented on MNG-2823:
-----------------------------------
The biggest offender I know of is:
{noformat}
Downloading:
http://ws.zones.apache.org/repository2//org/apache/geronimo/genesis/config/project-config/1.1/project-config-1.1.pom
[WARNING] Unable to get resource
'org.apache.geronimo.genesis.config:project-config:pom:1.1' from repository
axis2-m2-repo (http://ws.zones.apache.org/repository2/)
{noformat}
I put the "Downloading: ..." line in here too, since they seem to go hand in
hand. Would be nice to *only* show "Downloading: ..." when its actually there
to download, else log a DEBUG about "Attempting to download: ..."
This one does not show up much, but more often than not its not a problem:
{noformat}
[WARNING] Unable to load parent project from repository: Could not find the
model file '/Users/jason/ws/geronimo/server/../pom.xml'.
{noformat}
This is a lame duck warning (should not log this, since the expected prefix
matches what's there)
{noformat}
[WARNING] Goal prefix is: geronimo; Maven currently expects it to be geronimo
{noformat}
Some places the ^^^ warning actually shows a problem, though with all the
"Unable to get resource" I tend to miss them.
And then a few of these:
{noformat}
[WARNING]
Artifact org.apache.xbean:xbean-finder:jar:2.8:runtime retains local scope
'runtime' overriding broader scope 'compile'
given by a dependency. If this is not intended, modify or remove the local
scope.
{noformat}
I've yet to run into a situation where I wanted to change the scope based on
this message, usually the scope was correct. So its a little bit more noise to
sort though.
But, the biggest one is the first... I have ~2k of these messages in a Geronimo
server build. If nothing else I'd like to see that log become a DEBUG message.
And the WARNING about the plugin prefix should be removed unless the prefix
configured doesn't actually match what is expected.

> It would really be nice if there was more control over what WARNING messages

> output... which really makes it hard to see what is actually going on.
> I'd like mvn to not show those by default, and have a flag to enable them if
> needed... kinda like the -W flag on gcc.
> IMO these WARNING messages are only useful about 5% of the time when strange
> dependency problems pop up... it would be better IMO if for the remaining 95%
> that mvn didn't complain so much about stuff that is not really a problem.
