So I’ve fixed my CVS/Maven issues. It turns out that you need to specify a CVS repository like:
scm:cvs:pserver:anonymous@cvs.sourceforge.net:/cvsroot:classifier4j
rather than
scm:cvs:pserver:anonymous@cvs.sourceforge.net:/cvsroot/classifier4j
Apparently, this is assumed knowledge or something, or is just a CVSism.
I was basing my setting on the sourceforge documentation:
cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/classifier4j login
cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/classifier4j comodulename
The SF documentation is usually quite good… Oh well… the joys of different development environments.
