http://www.jfrog.org/sites/artifactory/latest/source-repository.html contains howto checkout
$ svn checkout https://artifactory.svn.sourceforge.net/svnroot/artifactory/trunk/artifactory-site artifactory-site
(My experience with the "project documentation" is that the maven artifactId of the "pom" project should be the same as the directory name of this. You probably called it artifactId="artifactory-site" .. just change it to "artifactory" ... and it will work)
I realized it could be svn checkout https://artifactory.svn.sourceforge.net/svnroot/artifactory/trunk artifactory
I later tried to build the software. by ...
It failed, it also turned out to be version 1.3 .. so the documentation goes on the developer version... thats great...
I'm just missing the story.. how do I build the releases?
It would be very nice to have the build process described
mvn install -Pjfrog, ext
this was much better, but still som dependencies failed to be downloaded.
