Hello,
I think there must be a misunderstanding somewhere. What I proposed in
the best practices workshop is to separate the implementation of the
plugin interface (let's call it A) from the code actually doing the work
(let's call it B). A should only care about plugin specific things and
use the api of B. A is in the default package and has an underscore in
the name. B is not in the default package. B can be distributed over
many packages each part being in a package according to what it does.
The main advantage of this scheme is that the functionality of your code
is available as a library, that can be used from any other code, without
passing by the ImageJ "run" mechanism.
To install your plugin, you can create a .jar containing all the
packages used by B and put the jar and the class file of A in a
subfolder of the plugin folder.
Best regards,
Volker Bäcker
