problem with downloading jdepend-plugin

[exquisitus]

Hi,
 
I have a problem when I try to add the JDepend-reports plugin to maven2.
 
Adding this in the POM: (from
http://mojo.codehaus.org/jdepend-maven-plugin/howto.html) 
      <reporting>
          <plugins>
              <plugin>
                 <groupId>org.codehaus.mojo</groupId>
                 <artifactId>maven-jdepend-plugin</artifactId>
                 <version>1.0-SNAPSHOT</version>
              </plugin>
          </plugins>
      </reporting>
 
 
results in:
 
[INFO] ----------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ----------------------------------------------------
[INFO] Failed to resolve artifact.
 
GroupId: org.codehaus.mojo
ArtifactId: maven-jdepend-plugin
Version: 1.0-SNAPSHOT
 
Reason: Unable to download the artifact from any repository
 
  org.codehaus.mojo:maven-jdepend-plugin:pom:1.0-SNAPSHOT
 
from the specified remote repositories:
  central (http://repo1.maven.org/maven2),
  jibx.sf.net ( <http://jibx.sf.net/maven2> http://jibx.sf.net/maven2)
 
 
Has anyone an idea ?
thanks
