Git clone

• Now we will add the required libraries. This step will be removed when all third libraries will be validated by Eclipse.
• Download the libraries from this link: http://wiki.eclipse.org/OM2M/Download
• Extract OM2M-libs and add the following libraries to "org.eclipse.om2m" repository as follows:
  • "db4o-core-java5-8.1-SNAPSHOT.jar" library under "org.eclipse.om2m.core\libs",
  • "obix.jar" library under "org.eclipse.om2m.commons\libs",
  • "xsd" folder under "org.eclipse.om2m.commons\src\main\resources".

Build OM2M using maven

• Before building the OM2M project, you need to add “Tycho” to Maven plugin. (Why? more details) To do so, click Window -> Preferences -> maven -> discovery -> open catalog and type Tycho. Check the “Tycho Configurator” checkbox.

Git clone

• Select “org.eclipse.om2m” package and right click. Select “Run as -> maven install”.
• Two Eclipse products will be generated after a successful built:
  • The NSCL product can be found on this directory: "om2m/org.eclipse.om2m/org.eclipse.om2m.site.nscl/target/products/nscl/<os>/<ws>/<arch>"
  • The GSCL product can be found on this directory: "om2m/org.eclipse.om2m/org.eclipse.om2m.site.gscl/target/products/gscl/<os>/<ws>/<arch>"

Develop your interworking proxy unit plugin

We will start this section by demonstring how to create an interworking proxy plugin and associate it to the om2m platform. Then, we will implement this plugin by adding a MonitorSample class to simulate a sensor behavior and a ControllerSample class to manage a simulated actuator.
