“Provisioning agent not found” when closing Eclipse runtime

Question

When closing the runtime of my Eclipse plugin I get following error message:

!ENTRY org.eclipse.core.resources 4 2 2012-04-19 18:44:18.200
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.core.resources".

Can anyone tell me what I am missing?

Answer 1

As Alexander pointed out I was missing the equinox plugin org.eclipse.equinox.ds which was not added automatically by Eclipse, not even after "Add Required Plug-ins".

Answer 2

As this thread illustrates, when you are clicking "Add Required Plug-ins", and are still missing packages (like, in your case "org.eclipse.equinox.ds"), that can be linked to the type of project you are using:

You'll do yourself many favors if you change your build to a feature-based build and use the org.eclipse.rcp feature: it Includes all the necessary bundles for an RCP app, including org.eclipse.equinox.ds and .event.
