I have a simple RCP application prototype that was initially developed
on Eclipse 3.1. When checking out the code with Eclipse 3.2, all of the
"org.eclipse" imports are marked as unresovable. For example,
import org.eclipse.core.runtime.IPlatformRunnable;
in Application.java. The "quick-fix" suggested is to add "Plug-in
Dependencies" to the build path. When I do that, it appears in the
build path, but no jars are in it. When I create an RCP application
from scratch using the new project wizard, the Plug-in Dependencies has
all the expected jars in it.
Is there some migration steps that need to be followed? Some lingering
cache files that were accidentally checked into Subversion and are
causing problems?
Thanks,
Nathan

To answer your questions, I am trying to do both. The current version of
the app is being upgraded to run on 3.2.1, and it will also be developed
on 3.2.1. There are earlier versions of the app that run on 3.1.2, and
are in maitenance mode; consequently, I only want to develop on 3.2.1
for these earlier versions of the app.
I mananged to figure it out. As suggested, for the earlier versions of
the app, I changed the target platform to point to my 3.1.2
installation. After doing this, the older plug-ins were visible, but I
still had a bunch of unresolved compiler errors. I starting importing
the 3.1.2 plug-ins into my workspace as binary plug-in projects, and
this resolved the compiler errors. Once I create my MANIFEST.MF, will I
still need to import the 3.1.2 plug-ins into my workspace?

I should have mentioned that one of the plug-in projects in my workspace
is JFace (including source), and it of course does have a MANIFEST.MF;
however, I was getting a lot of compiler errors in the jface project
until I started importing its dependencies into my workspace.

I wanted to go through this process again so I started with a fresh
install of Eclipse 3.2.1. And this time around setting the target
platform was all I needed to do. I did not have import any plug-in
projects. I wonder if it was just a case of my workspace resources being
out of sync with the IDE before.
