maven.dependency.classpath seems to be corrupt

[Kanzlers, Andreas]

Hi,
I tried to reference the maven.dependency.classpath within the <tasks> element 
of the maven-antrun-plugin.
The logging of the classpath with
 
  <property name="dep.cp" refid="maven.dependency.classpath"/>
   <echo>${dep.cp}</echo>
 
produces following sample output:
 
  [echo] 
C:\svn\coremedia\slave\svnant;C:\svn\coremedia\slave\svnjavahl;C:\svn\coremedia\slave\jar;C:\svn\coremedia\slave\1.0.0;C:\svn\coremedia\slave\compil
e;C:\svn\coremedia\slave\junit;C:\svn\coremedia\slave\3.8.1;C:\svn\coremedia\slave\test;C:\svn\coremedia\slave\coremedia;C:\svn\coremedia\slave\cap;C:\svn\corem
edia\slave\5.0.545;C:\svn\coremedia\slave\svnClientAdapter

Only the folders of the dependencies are added but not the jars themselves.
(The maven.compile.classpath does include all the jars).
 
System: Windows XP, JDK 1.5.0_10, Maven 2.0.6 , maven-antrun-plugin 1.1,  
 
 
Any ideas ?
 
Regards,
Andreas
