"Add Required Plug-ins" button in Eclipse RCP product configuration?
eclipse-rcp
Solution
When you develop your RCP application, you specify:
- not enough plugins (i.e. only the one you need to compile, but not their runtime dependencies)
- and/or too many plugins (i.e. you depends on some provided by eclipse, even though you do not use them all)
In order to launch your RCP application as a standalone application, the "Add Required Plug-ins" allows you to validate (i.e. select only the right amount of plugins you actually need) your runtime configuration.

That helps to solve errors like:
- "One or more bundles are not resolved because the following root constraints are not resolved" or
- "java.lang.RuntimeException: No application id has been found."
Not; you can validate your plugins in order to check that launching configuration before actually launching it.
Problem
I don't quite understand what plug-ins constitue the list Dependencies when I make a product configuration in Eclipse RCP and what does the button "Add Required Plug-ins" exactly do? Why the Dependencies list is not full from the very beginning and why I have to use that button? Thank you.
