Description Corey Ashford CLA 2012-01-24 21:15:12 EST 
Build Identifier: M20110909-1335

I've run into a strange problem that I hacked in a fix for before, but then forgot about it.  Now that I'm trying to create a coherent patch series to post up, I ran into my hack, and removed it, and of course the old problem re-appeared.

The problem is that in the class ProfileUIUtils.java, there are two methods from
CCorePlugin used: getDefault() and getIndexManager().

When I build the org.eclipse.linuxtools.profiling.ui, I get unresolved references to these two functions.

If I navigate to the class, clearly these methods are there, and I don't understand why Eclipse isn't seeing them.

After scratching my head for a bit at this, I tried changing the dependencies
in META-INF/MANIFEST.MF from packages to bundles, and somehow that fixes the problem.

Reproducible: Always

I will take a longer look at this later, but Import-Package is preferred over Require-Bundle.
Comment 3 Corey Ashford CLA 2012-01-25 13:58:34 EST 
I read up on a blog post about bundle vs. package dependencies, and I understand why package dependencies are preferred.

Andrew, have you run into this particular build problem before?

I've cleaned my workspace completely, re-built, and the problem persists.  It's
very strange.  It's almost as if Eclipse is looking at at an old version of
the class definition, or its parent, or I don't know what...

In the source editor, it appears that Eclipse can see only these members of CCorePlugin:

CDT_PROJECT_NATURE_ID_MISMATCH
class
PLUGIN_ID
STATUS_CDTPROJECT_EXISTS
STATUS_CDTPROJECT_MISMATCH
STATUS_PDOM_TOO_LARGE
createStatus(String msg)
createStatus(String msg, Throwable e)
getResourceString(String key)
log(IStatus status)
log(Throwable e)

I can build o.e.l.profiling.ui just fine.  I just started a clean workspace with a recent Eclipse 4.x build and it continues to build just fine for me.

Could your target platform be set incorrectly?

Closing the bug as there haven't been any reply and profiling.ui builds fine in hudson.
