Unexplained dependency cycle [message #249966]

In a project I'm working on we're seeing some unexplained (to us)
dependency cycles when trying to build/export our app.
They look similar to this:

A cycle was detected when generating the classpath
com.company.core_1.0.0, org.eclipse.jdt_3.3.0.v20070607-1300,
org.eclipse.ui.cheatsheets_3.3.0.v20070507, com.company.core_1.0.0

When we remove org.eclipse.jdt from the com.company.core dependencies,
this error goes away. And that’s fine right now since com.company.core
doesn’t actually depend on org.eclipse.jdt, but I’m still very curious
where this cycle is coming from. I can’t for the life of me figure out
how org.eclipse.ui.cheatsheets ends up depending on our com.company.core
plugin.

Any insight? Any reference material we need to brush up on about this?

TIA,
Eric

If you look at the Plug-in Dependencies view and at the current state,
do you see anything there that would cause the cycle?

No, I didn't spot anything there; but I'll admit that I'm not 100% sure
I am interpreting that view correctly (although it seems pretty obvious).
As I said, I really don't understand how an org.eclipse plugin can be
depending on one of our plugins. Is that what the error is trying to
tell me?

"A cycle was detected when generating the classpath
com.company.core_1.0.0, org.eclipse.jdt_3.3.0.v20070607-1300,
org.eclipse.ui.cheatsheets_3.3.0.v20070507, com.company.core_1.0.0"

I suppose that you have a fragment for the org.eclipse.jdt plugin (or
for some other Eclipse plugin) that depends on your com.company.core plugin.

Thanks for the lead - it would definitely explain the situation.
Unfortunately, I looked at our fragments (we only have a couple) and
none of them specify any org.eclipse plugins as their host; they are
only hosted by our own plugins.
