To be able to develop new Steps, you should have an OSGi framework installed and set up within Eclipse.
In general, it is possible to use any OSGi implementation, but for convenience, this guide will show you how to install Eclipse Equinox as the OSGi framework.

• Download Eclipse Equinox:

  Go to http://download.eclipse.org/eclipse/equinox/ and download the Equinox Software Developement Kit:

  For these examples, version 3.4 is used.

  eclipse-equinox-SDK-3.4.zip

  Extract it to any location.

• Setting up Eclipse Equinox:

  In Eclipse, go to Window → Preferences.

  Select Plug-in Development → Target Platform.

  Click Add...

  Initialize the target definition with: Nothing

  Give any name for the target and create a new target location.

  Click Add... and select the directory where you extracted the Equinox SDK.

  

  For Example

  eclipse-equinox-SDK-3.4/eclipse

  

  Select your new target and click OK

  
• Done!

  You are now ready to develop new OSGi-Bundles with Eclipse.

  Continue with Importing Anna-Plug-ins in order to import Plug-ins for development of new pipeline Steps.
