-5. Install **Eclipse EE**. A different Java development IDE (or none at all) can be used, but the Vipra projects are made with eclipse and come with settings and run configurations. Install the M2Eclipse plugin for maven support in eclipse, if not yet installed. The plugin will download the required project dependencies and manage the project configurations, build versioning and packaging. Set up the installed Java EE application server in Eclipse. Add the `vipra-backend` project to the web server.
