eclipse plugin development: migration error from eclipse 3.2 to 3.6

[Franz Mayer]

Hi,

I am not sure, if this is the correct forum for this question, but I haven't found any other.

I inherited a quite old RCP-project from a former collegue of mine. The RCP-project was developed in eclipse 3.2.2. When I try to start the application with eclipse 3.6 (Helios) it returns (amongst others) following error:

org.osgi.framework.BundleException: The bundle "org.eclipse.core.runtime_3.6.0.v20100505 [3]" could not be resolved. Reason: Missing Constraint: Require-Bundle: org.eclipse.equinox.common; bundle-version="[3.5.0,4.0.0)"

However the package "org.eclipse.equinox.common_3.6.0.v20100503.jar" is found by eclipse and it is listed under "Plugin-in Dependencies".

As I am new to RCP-development, I do not know where the error could be. How can I locate the error? And where could I get more information about RCP-Development (also forums)?

Thank you,
Franz

I found now a forum, which should be situable: Forum "Rich Client Platform (RCP)" under http://www.eclipse.org/forums/

Unfortunately I haven't found any hint to the error yet.

If anybody has an idea, how I can trace the error, I would be glad.
