The Caller plugin is an interface abstraction for goals. It defines several Well-Known Goal Interfaces (WKGI). This allows a plugin to call another plugin through this Caller plugin. The benefit is that it is then possible to rewire the implementation of a WKGI.

Then, in your Aspectj plugin, you would call
<caller:set goalInterface="compile-java" goal="aspectj:compile"/>
Thus, when, as a user you will call the
