Start the workspace with the -clean option after any configuration change. After the first time you start Eclipse, it caches the loaded plugin settings under eclipse/configuration/. If you changed the install of your Eclipse shell (e.g. added additional dependencies, replace jar files etc.) and these changes conflict with the cached settings of eclipse, the cached ones will be used. Either use -clean or remove the plugin folders under eclipse/configuration/ (except the config.ini file), and try again.
