1. Upgrade Any23 dependency in src/plugin/any23/ivy.xml

2. Upgrade Any23's own dependencies in src/plugin/any23/plugin.xml
   To get the list of dependencies and their versions execute:
    $ cd src/plugin/any23/
    $ ant -f ./build-ivy.xml
    $ ls lib | sed 's/^/      <library name="/g' | sed 's/$/"\/>/g'

   In the plugin.xml replace all lines between
      <!-- Begin Any23 dependencies -->
   and
      <!-- End Any23 dependencies -->
   with the output of the command above.

3. Remove the locally "installed" dependencies in src/plugin/any23/lib/:

    $ rm -rf lib/

4. Build Nutch and run all unit tests:

    $ cd ../../../
    $ ant clean runtime test
