Hi Craig,
in case, you're building Nutch from the git repo or from the source package
the easiest way is to put the file NewCustomHandler.java into
src/plugin/protocol-interactiveselenium/src/java/.../handlers/
and run
ant runtime
to compile and package Nutch including package your custom handler.
Using a jar isn't as simple, mostly because of the classpath encapsulation
of Nutch plugins.
1. add you jar as a dependency to
src/plugin/protocol-interactiveselenium/ivy.xml
2. register the file name of the jar in
src/plugin/protocol-interactiveselenium/plugin.xml
as
3. build Nutch, see above
Of course, ivy must be able to pick the jar from one of
the repositories listed in
ivy/ivysettings.xml
But it's possible to add your local Maven repo/cache by adding:

There are some handler implementations in
src/plugin/protocol-interactiveselenium/src/java/.../handlers/

at the first glance, because one file name includes a typo. :)
If you have time please open a Jira issue at
https://issues.apache.org/jira/projects/NUTCH
to fix the naming.
Thanks,
Sebastian
