The build log with -X -e might help sussing that out..it might have to
do with the fact that the dependency resolution in Maven 3 is done with
a different library (aether) but could something different too..
And in terms of the file repo. Just install e.g. Nexus and copy it into
the sonatype-work folder as a repo and you are up and running with a
proper repo (and maybe get rid of any junk in there..)

Manfred,
Ok thanks, I will look into doing that with the simple example. Unfortunately I
cannot get rid of the proxy server as I am behind a firewall here and that is
the only route out. However the two maven repository servers could be a better
way to handle the proxy and the repositories. I have inherited the older
file:// proxy from previous developers.
However, I still don't understand how come this project builds with no issues
under maven 2?
Cheers,
Martin

Most likely your problem is related to the proxy in settings.xml or the file://
repository in the pom.
I would remove your pom.xml and try to build a simple project like the simple
example from the maven book
https://github.com/sonatype/simple-example
Ideally without the proxy.
In either case I would suggest to look at using a repository server like Nexus
or Artifactory or Archiva to simplify these issues.
Using a file:// repository is definitely a bad idea.

Manfred,
Thanks for the reply and the tip about pastebin - never heard of it.
I have created two pastes in the pastebin
My pom.xml http://pastebin.com/dRtyGVGz My settings.xml
http://pastebin.com/NHK60YBG
All the documentation that I have seen so far has suggested exactly as you say
that maven 3 and maven 2 are compatible. If you would like the error output
from the maven 3 build I can supply that as well.
I can remove my entire local maven repository and get maven to download
everything again to see if this helps?
Cheers,
Martin

Maven 3 should be a drop in replacement. You might have to show us your
settings file.
Also I would get rid of the manually installed artifacts since they most like
dont have the pom file (unless you added it as well) and will cause you issues.
In terms of file you will have to use pastebin or a gist since no attachments
are allowed on this list.

Hi,
I am just getting up to speed with maven and I have a couple of projects that
use maven. I have been fighting with maven / dependencies / mirrors and
repositories for the better part of a week now with my projects always ending
up with being unable to resolve dependencies. Usually on a bunch of the same
jar files (commons-lang, commons-discovery - to name a couple).
I am using maven 3.0.3 with jdk150_12.
What I have found out is that I can manually install these jar files into my (what I
assume to be local repository) using mvn install:install-file command. I get the correct
successfully updated response to this command and re-run my mvn clean install command.
Only to find that the result is exactly the same "build failure" with the same
jar files being not found.
If I look into my local repository and follow the artifact/group/version path I
see my jar file is happily sitting there, but for some reason is not recognised
or found.
I dont understand how come it appears to me that maven 3.0.3 is not looking at
my local repository for my files?
Also how come everytime I run the command mvn install maven 3.0.3 goes off into
the internet and tries to download all the files again?
I did some further investigation into the problem and actually went and got the
binaries for maven 2.0.11. I updated my path variables and then re-ran my build
on the project under maven 2.0.11 using mvn clean install. This time after an
age of downloading and updating files the project successfully built. I have
not changed any source code in the project or altered the pom file (which maybe
the issue) in any way.
I understood that maven 3 is backwards compatible with maven 2 projects?
Is there any tutorials / migration paths / updates that I need to apply to my
pom file to build the application under maven 3.0.3?
I attached the pom and settings files and I can provide the environment paths
etc required and I also have a list of missing jar files that are causing the
issue that I can supply as well.
I would like to build the project under maven 3 or at least understand why the
project is not or cannot be built under maven 3.
Any help on this would be greatly appreciated.
Thanks,
Martin Sweeney
