It looks like you're missing a required library.

This class is located in the jpf (Java Plugin Framework) library which is
included as a dependency of the core project.  If you're including the core
project/lib as a dependency then you should automatically get jpf as a
transitive dependency.

Are you using gradle to build your project?

Your project will need an osmosis-plugins.conf file containing the name of
your plugin loader class, but otherwise that should be all you need so long
as you have all the necessary jars available on your classpath.
