RCP based on plugins or features?

I have an RCP application based on plugins because I started this app from a simple Mail example.

I am now wondering what is the difference between an RCP application based on features compare to one based on plugins ?

For information,开发者_运维百科 my RCP will maybe require some advanced features such as headless build, or self update. May be this can impact on the choice of using plugins or features as basis?

Since features are just a collection of plugins (aka, a "packaging" process), you should be able to do in a PDE headless build what you can do with the PDE GUI.

The PDE build page does mention:

Building plug-ins, fragments or features consists of the 3 stages: fetch, generate scripts and build that are described bellow.

You could have some issue for modified plugin, but building features or a final product should work.
