My GEF plugin needs a Properties tab.I added the interface IPropertySource .
It throws an exception at runtime as follows:
java.lang.NoClassDefFoundError: org/eclipse/ui/views/properties/IPropertySource
at org.eclipse.gef.internal.PropertySourceAdapterFactory.getAdapter(PropertySourceAdapterFactory.java:33)
at org.eclipse.core.internal.adapter.AdapterFactoryProxy.getAdapter(AdapterFactoryProxy.java:82)
at org.eclipse.core.internal.runtime.AdapterManager.getAdapter(AdapterManager.java:301)
at org.eclipse.gef.editparts.AbstractEditPart.getAdapter(AbstractEditPart.java:464)
at org.eclipse.gef.editparts.AbstractGraphicalEditPart.getAdapter(AbstractGraphicalEditPart.java:461)
at org.eclipse.ui.internal.views.ViewsPlugin.getAdapter(ViewsPlugin.java:104)

I have added "org.eclipse.ui.views" in my dependencies.

Not able to debug why the same is happening.
Kindly guide.
