+== Build (Parameter Catalog) Applications with Eclipse Tycho
+
+Three plugins so for for the content and UI.
+
+Missing: Deployable application and inclusion to third party libraries.
+
+Building an application "around" the three plugins for Ecore data model and UI specification model.
+
+See template.

+=== Use Maven and Tycho as Build System
+
+.Install Maven Support
+
+We are going to create a complete Eclipse desktop application from generated code.
+We also want to deploy this application for Linux, macOS and Windows operating systems.
+Eclipse offers several approaches for compiling and deploying such an application, traditionally with _Ant_ scripts.
+
+Creation and maintenance of these scripts turned out to be tedious and error prone.
+For quite some years now, the proposed -- and mostly supported -- method for building Eclipse applications is to use _Maven_ build system, more specifically, a couple of Maven plug-ins, subsumed under the name _Tycho_.
+
+Many Eclipse platforms have Maven support https://www.eclipse.org/m2e/[_M2Eclipse_] already built in, not so our _Eclipse Modeling Tools_.
+But don't worry: Installation of required Eclipse feature is easy and straight forward.
+And, by the way, you will acquire the indispensable skill of how to install new plug-ins/features to Eclipse.
+
+First, tell your Eclipse installation where to look for the new software.
+Execute `Help -> Install new Software...` to invoke dialog _Available Software_ and press `Add...`.
+Sub-dialog `Add Repository` pops up.
+
+.Add update site m2e 
+image::InstallMaven1.gif[InstallMaven1, role="thumb"]
+
+In there provide `m2e` as name and
+
+ http://download.eclipse.org/technology/m2e/releases
+
+as location.
+After confirmation with `Add`, Eclipse now looks up the site for available software. 
+
+.Choose features to install

+
+Check the items to install like shown above and confirm all following questions about licenses and security concerns.
+After download is complete -- it can take a few minutes -- restart Eclipse.
+Verify that Maven version 3.6.3 or above is now installed in `Window -> Preferences...` (or `Eclipse -> Preferences...` on macOS) under `Maven -> Installations`.
