I have build both connector plugins (core, ui) in Eclipse 3.2.1 (but not the other Mylar 3.2 projects, do I need them?) and I can even debug the connector in Eclipse 3.2.1.
But when I try to export it and deploy it, I am getting error:

Root exception:
java.lang.ClassNotFoundException: org.eclipse.mylar.internal.codebeamer.core.CodeBeamerCorePlugin
at org.eclipse.osgi.framework.internal.core.BundleLoader.findClass(BundleLoader.java:402)

Even if both ...core.jar and ...ui.jar for the connector are in plugins directory (with other Mylar 1.0.1 stuff).

Man this should be easier than it seems. So far I can deploy in Eclipse 3.3M4 only but I can debug in Eclipse 3.2.1 and 3.3M3, but not in 3.3M4.

Lubos: I assume that you got this resolved. PackageFragmentRootContainer is an Eclipse 3.3M4 only class, so if you were building against 3.3M4 correctly you should not have had the compiler error. I put some notes on what HEAD and related branches support here:

Subject: [mylar-dev] Problems doing development after CVS update to HEAD (1.0.1)

Few days ago I have updated all Mylar projects in my development area to HEAD (1.0.1).
I am running on Eclipse 3.3M3 and Java JDK1.5_09.

I got compile errors in org.eclipse.mylar.internal.java.JavaStructureBridge related to package:

import org.eclipse.jdt.internal.ui.packageview.PackageFragmentRootContainer;

If I ignore the errors or edit the file to remove references to PackageFragmentRootContainer, everything works fine.

I figured out, that it is time to upgrade to Eclipse 3.3M4, but when I do that and start debugging the CodeBeamer connector
I am developing (almost there, just need some more testing), I get a lot of errors in the debugged application, and my connector
does not appear in the Task Repositories dialog any more.

I switched back to 3.3M3 and edited JavaStructureBridge so I do not get errors any more. So for now I can develop with Eclipse 3.3M3.
But ultimately I would like to switch to Eclipse 3.3M4.

Anybody has a suggestion how to fix the problems, so I can continue developing with Eclipse 3.3M4?

Here are the errors from the application (Codebeamer Connector UI) debugged in Eclipse 3.3M4:
(looks like the core of the problem is: java.lang.NoClassDefFoundError: org/eclipse/mylar/internal/codebeamer/core/CodeBeamerCorePlugin).
There are a few other problems after that all related to this first one.
