AJDT has no special support for managing plugin dependencies as far as I 
know. You could probably make this work by dealing with the dependencies 
by hand, but that is maybe not what you want.

The dependency management is somewhat tricky when you combine aspects 
and plugins. The easiest way to deal with this is to use the Equinox 
Aspects incubator project. It adds load-time weaving to the Equinox OSGi 
runtime. Using this extension to OSGi you can put your aspects into 
bundles and the weaving (and most parts of the dependency management) 
happens at load-time:

There are different settings possible how to use aspects in the context 
of plugins. I would recommend taking a look at these presentation of 
this EclipseCon talk:
