Workflow 

# yum install maven2 rpmdevtools
$ cd ~
$ mkdir -p rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS,TMP}

create ~/.rpmmacros with content (or more if you want): 

%_topdir      /home/gijs/rpmbuild
%_tmppath     /home/gijs/rpmbuild/TMP
%_gpg_name             Gijs Molenaar <gijs.molenaar@surfnet.nl>

The last line is for signing of the packages, you can specify the key to use (if you want to sign) 


$ cd ~/rpmbuild/SOURCES
$ wget surfnet_java-flowsa-ma-<VERSION>.tar.gz
$ cd ~/rpmbuild/SPECS
$ cp ../BUILD/surfnet_java-flowsa-ma-<VERSION>/contrib/surfnet_java-flowsa-ma.specs .
$ rpmbuild -bb ~/rpmbuild/SPECS/surfnet_java-flowsa-ma.specs

RPM will be in ~/rpmbuild/RPMS/noarch

I've used the fedora RPM guide a lot: http://docs.fedoraproject.org/drafts/rpm-guide-en/
