Hi Martin, If you look closely at the log it "downloads" from /usr/share/maven-repo. It isn't fetching jars from a remote repository but copy them from the local repository.
I confirm that scala depends on itself. Did you remove it from the build dependencies? Emmanuel Bourg __ This is the maintainer address of Debian's Java team <http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-java-maintainers>. Please use [email protected] for discussions and questions.
