Usually we tend to develop everything inside the Nutch file structure, specially useful if you need to deploy to a Hadoop cluster later on (because you need to bundle everything in a job file).
But, if you really want to develop the plugin in isolation you only need to create a new project in your preferred IDE/maven/ant/gradle and add the dependencies that you need from the lib/ directory (or the global dependencies with the same version). Then just compile everything to a jar and place it in the proper plugin structure in the Nutch installation. Although this should work is not really a smooth development experience. You need to be careful and not bundle all libs inside your jar, etc. The path suggested by Sebastian is much better, in the end while developing you want to have everything, perhaps just compile/test your plugin and later on you can copy the final jar of your plugin to the desired Nutch installation.
