SciJava Common is a shared library for SciJava software. It provides a plugin framework, with an extensible mechanism for service discovery, backed by its own annotation processor, so that plugins can be loaded dynamically. It is used by both ImageJ and SCIFIO.

There is a newer version: 2.99.0

/**
 * {@code Command} is a plugin that is executable. A {@code Command} can be

 * {@link CommandModule}.

 * annotated with @{@link Plugin} with attribute {@link Plugin#type()} =

 * {@link ContextCommand} (or in some cases {@link ModuleCommand},
 * {@link DynamicCommand} or {@link InteractiveCommand}) for convenience.
