It seems to fail when trying to restore the workspace.
Try:
-
Open a new workspace. If it has been set to use a default, go to
<Eclipse_root_dir>\configuration\.settings\org.eclipse.ui.ide.prefs
and setSHOW_WORKSPACE_SELECTION_DIALOG
to true -
Try deleting
<workspace>/.metadata/.plugins/org.eclipse.core.resources/.snap
-
As suggested in a comment: If using Eclipse 4, you may have to delete the file
.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
aswell.
