Sorry if this is the wrong place. I didnt see exactly where to post it. In my eclipse (3.3.2) I am getting an error "XXX class cannot be resolved.It is indirectly referenced from required .class files"

Problem is its clearly there. I saw in previous posts that some users are changing the installed jre's to sort of "reset" it. I tried that but no luck.
What else can I do?

Are these plugin projects you're working on? I imagine so. Generally
you should find out which bundle contains that class and add that bundle
to the dependencies of the MANIFEST.MF.

That doesn't answer whether your developing bundles or not... You might
have a jar x.jar that has classes A and B. You might be able to import
A fine, but B might depend on C and C might not be in x.jar so you'll
find B can't be imported without this problem. It might be in y.jar, so
you'll need to find where C is defined and be sure the jar for it is in
the classpath. If you're developing bundles, you do that by editing the
MANIFEST.MF.

Have you figured out which jar contains the class it's complaining
about? Ctrl-Shift-T might help.

So if I do the ctrl+alt+t I can find the class its complaining about but it says "source not found" when opening it<- I assume thats my problem or is it ok as long as its found?
Forgive me... I spent 8 yrs as a smalltalk developer and am scratching my head how all these associations work.

So, I clicked on "attach source" and choose the jar file I know I need and nothing changes(wasnt sure if this is my issue)

There might not be any source, but you do need to locate the jar so you
can add it to your classpath. I can't tell you where it is.

It seems likely that you added x.jar to your project's build path, but
x.jar depends on another JAR, y.jar, that isn't on your project's build
path. In that case, you need to add all JARs that x.jar depends on.
If you gave details, such as the JAR(s) you've added and the class's
that are listed in the error(s), our help could perhaps be more specific.
