Vaadin Plug-in for Eclipse

I have been trying to install the Vaadin plug-in for Eclipse over the volume for weeks. The installation ends each time with the error message: “No repository found at http://vaadin.com/eclipse/”. From home, the installation works flawlessly and easily. I am concerned that the cause of the reliable crash is the company firewall. Does anyone know if you can download the plugin as zip and install offline? Any ideas?

Thanks and Regards,
Gregory
