Getting Started


The Libra project enables you to use tools that integrate the existing WTP tooling and PDE tooling so that OSGi Enterprise applications can be developed with both tooling at the same time. It also provides you with tools for better experience in the Server-Side Equinox scenario.

Installation and Use

Currently Libra supports only Eclipse Indigo. As a prerequisite you need to installEclipse IDE for Java EE Developers and Libra from this update site

The update site contains:

  • OSGi Facet Feature that introduces:
    1. A new facet "OSGi Bundle" for Dynamic Web, JPA and Utility projects.
    2. Wizard for converting WTP standard projects to OSGi Enterprise bundle projects:
      • Dynamic Web projects to Web Application Bundle projects
      • JPA projects to Persistent Bundle projects
      • Utility projects and simple Java projects to OSGi Bundle projects
Both options modify project's MANIFEST.MF in order to become a valid OSGi bundle.

The facet may be enabled during project creation or after that from Properties page of the project. The wizard is available from project's context menu Configure > Convert to OSGi Bundle Projects...

Note that you may need to adjust your target platform accordingly.


Obtaining Sources

You can find the sources available in Git repository
In order to synchronize them locally, you may use EGit step-by-step procedure Screenshot


The build is based on Maven(at least 3.0.0) and Tycho, executed on Hudson server, hosted at Eclipse Foundation.

Maven Build Sequence

[~/org.eclipse.libra/development/org.eclipse.libra.releng] $ mvn clean install
 Note that you may need to configure your proxy settings
