[Geotools-gt2-users] Newbie: Can't compile geotools svn

[Nicola R. <nic...@gm...>]

Hi all,
I can't compile geotools from the svn. mvn aborts with this message:
----------
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Failed to resolve artifact.

Missing:
----------
1) org.geotools:gt2-build-configs:jar:2.3-SNAPSHOT

  Try downloading the file manually from the project website.

  Then, install it using the command:
      mvn 
install:install-file -DgroupId=org.geotools -DartifactId=gt2-build-configs \
          -Dversion=2.3-SNAPSHOT -Dpackaging=jar -Dfile=/path/to/file

  Path to dependency:
        1) org.codehaus.mojo:jalopy-maven-plugin:maven-plugin:1.0-SNAPSHOT
        2) org.geotools:gt2-build-configs:jar:2.3-SNAPSHOT

----------
1 required artifact is missing.

for artifact:
  org.codehaus.mojo:jalopy-maven-plugin:maven-plugin:1.0-SNAPSHOT

from the specified remote repositories:
  codehaus.org (http://repository.codehaus.org),
  central (http://repo1.maven.org/maven2),
  snapshots (http://snapshots.repository.codehaus.org),
  codehaus-snapshot-plugins (http://snapshots.repository.codehaus.org/)
------

I've found on the net only jalopy-maven-plugin (not gt2-build-configs) I've 
installed but "mvn compile" show a warning:
[WARNING] Artifact org.codehaus.plexus:plexus-utils:jar:1.1:runtime retains 
local scope 'runtime' overriding broader scope 'compile' given by a 
dependency. If this is not intended, modify or remove the local scope.

Then aborts with the message that I pasted on top of this email.

How can I solve these problems and make geotools to compile ?
