there is a little project for me to make a java app which analyzes yours SVN repository files (history), in other words, you need to make a project. using this app you should get the history of changes made to a repository.
tried some examples (f.e. http://svn.svnkit.com/repos/svnkit/branches/sgk/doc/examples/src/org/tmatesoft/svn/examples/repository/History.java ) and only get error : "... cannot be resolved".

i even can't import those libraries. svnkit already installed.
