o.n.l.c.c.ComandException in maven-changelog-plugin

[Mario Ivankovits]

Hello !
I use Maven-1.0-rc3/cvslib-3.6 on windows xp.
I try to regenerate the commons-vfs site and during the changelog 
creation i get the following output

site:run-reports:
   [echo] Generating the Change Log...
maven-changelog-plugin:report:
   [echo] Generating the changelog report
*org.netbeans.lib.cvsclient.command.CommandException*
ChangeLog found: 0 entries
After some fiddeling around with the debugger i managed to get the 
following stacktrace out of maven

java.lang.NullPointerException

.....

After decompile the BasicCommand, line 150 is the following code
/* 150*/        for(index = 0; index < files.length; index++) {
so the only thing which could happen here ist that the files array is 
"null".

Issuing the command (using the cygwin-cvs.exe)
cvs -d :pserver:[EMAIL PROTECTED]:/home/cvspublic log -d 
"2004-04-26<2004-05-27"
brings a perfect log.

I already tried to checkout commons-vfs to a completely empty directory 
and retry the "maven site" command - same failure.
Even trying this on another machine doesnt change anything.

I tried Mave-1.0-rc2 too - with the same result (in fact rc2 was the 
first i got this failure, then i upgraded to rc3 - never used any maven 
version before)

Logging the network traffic on my firewall shows me, that the cvs 
communication is running.

This is something which already worked, i do not manage to find out what 
has been changed.
So now i do not know what to do next?

Any ideas??
Thanks,
Mario
