Fundamentally, p2 is a technology for provisioning and managing Eclipse- and Equinox-based applications. You can use p2 to install or manage any aspect of your application, from the physical plugins and native code, to the configuration of the installed software: file permissions, command line arguments, etc. Installation with p2 does not consist simply in adding or removing files in the file system, but more generally the sequence of events that must occur to lay down and configure a system that is ready to run.

- Define Name - e.g.
- Define URL for Remote storage - e.g.
- Select an appropriate Blob store
Browsing p2 Repositories and Searching Packages

Please uncheck checkbox 'Contact all update sites during install to find required software' for installing directly from NXRM.
Click Add button to add plugin source and put in the URL field the NXRM proxy repository URL (e.g.
Click Manage button if you want to manage your sources. There are some Eclipse sources here by default, you can disable them if you need just NXRM sources (deleting these resources will not lead to the desired result, they will appear again after the application is restarted).
Follow the instructions. After installation NXRM contains proxied package, as shown:
