Getting an error org/apache/maven/wagon/StreamWagon.openConnection()V

Hi,
I'm getting an error java.lang.AbstractMethodError:
org/apache/maven/wagon/StreamWagon.openConnection()V.

My settings.xml has the entry:.
<server>
      <id>csdpFtpRepository</id>
      <username>egaona</username>
      <password>password</password>
    </server>


Any idea how I can fix this?  Thanks
