As I mentioned in my first post, I followed the instructions from this article (http://docs.codehaus.org/display/MAVENUSER/Deploying+3rd+Party+Jars+With+WebDAV )
So it is not correct because it uses a bad url: -Durl=http://localhost:8080/archiva/repository/myrepo It would be nice to update this article and to explain that you have to use "dav" as wagon protocol Thanks, Rémy
