Can't prepare release...

[Mike Müller]

Hi

I need some further help to do my first release:
I ran into troubles when I try to execute

mvn release:prepare

The error below appears:
[INFO] ------------------------------------------------------------------------
[INFO] Trace
org.apache.maven.BuildFailureException: Unable to commit files
Provider message:
The svn command failed.
Command output:
svn: Commit failed (details follow):

authorization failed: Could not authenticate to server: rejec
ted Basic challenge (https://svn.apache.org)

I checked my settings.xml which seems to be okay:

<?xml version="1.0"?>
<settings>
  <localRepository>C:\dev\maven\repository</localRepository>

            </properties>
        </profile>
    </profiles>
</settings>

I also tried to put in my password in plain text, but no luck.
Did I missed something or do I have not enough rights to commit a release?

best regards
