1. Clean your projects
2. Clear your Eclipse workbench settings

How you can exactly do step #2 depends on your OS, but on Mac it is:

1. Go to your workspace
2. Open .metadata (you'll need to be able to see hidden folders for this)
3. Open .plugins
4. Open org.eclipse.e4.workbench
5. Delete workbench.xmi
