This file is an Eclipse update zip to be used from within an Eclipse installations update manager. Do not unzip this zip into Eclipse directly nor into its dropins folder - it will not work. In fact, you do not need to unzip this zip at all - you can simply use the Eclipse Update Manager ( Help > Install New Software... > Add... > Archive... ) to perform the installation directly from this zip file.
