I disagree that it should be difficult to stay uptodate with the main codeline if you have a lot of local changes.
You can put your code under local version control in subversion and then use the process described in the "Vendor branches" chapter of the subversion book (found here: http://svnbook.red-bean.com/nightly/en/svn.advanced.vendorbr.html) to stay uptodate with Nutch SVN. I upgraded my local version with several plugins and tweaks from 0.7.1 through 0.7.2 to the latest 0.8 nightly build this way without major problems. Good luck.
