Maven woes again

As Xdoclet uses Maven to produce the final documentation and web site, I thought I could enable the maven-statcvs-plugin to get to fancy line of code charts.
But instead:

[java] StatCvs-XML - CVS statistics generation
[java]
[java] java.lang.NullPointerException
[java] at net.sf.statcvs.Main.getModuleName(Main.java:193)

When looking at the documentation, I found out, that this plugin uses a cvs command found on the host, while the maven-changelog-plugin uses a built-in cvs client.
This explains why maven takes that much space *sigh*.

Even worse: both plugins get the change log from the cvs server. Instead of fetching it one time only and then processing it twice, the load on the server is doubled!
