2. 3.0

3. Build
• (Even) better build fidelity with offline.
• Faster, more scalable builds.
• All packaged code in dependent bundle visible
downstream.

4. OSGi Release 6
• Support for OSGi R6 annotations: DS 1.3 and
MetaType 1.3.
• Annotation processing for DS & MetaType enabled
by default.
• Versioning annotations from OSGi spec.
• Prefer package-info.java over packageinfo.

5. DS 1.3 Demo

6. Repo-Specific Deps
-buildpath: osgi.cmpn; version=5.0; repo="Build*,Release"

7. Capability Search

8. Wildcard Dependencies
-buildpath: *; repo=Build
• Can be used from cnf.
• Puts all bundles from the repo on buildpath.
• Enable type-level repo searches using ⌘T

9. • bnd-maven-plugin now production-ready.
• Use POM properties in bnd.bnd.
• Inheritance from Parent Project, omit bnd.bnd if
specific settings not required.
• Most projects don’t require bnd.bnd (this surprised
us too…)

10. • New “Non-Workspace” Plugin.
• Much better than the “official” Gradle OSGi
plugin… also, maintained!
• As used by Liferay.

11. 3.1

12. “Standalone” Operations
• Resolve/Run/Export without bnd Workspace.
• Better support for Maven and Gradle (non-ws) devs
• OSGi Repository Index wizard.

13. • Indexing (bnd-indexer-maven-plugin).
• Baselining (bnd-baseline-maven-plugin).
• Integration testing (bnd-test-maven-plugin).
• Export as executable JAR (TBD).

14. Standalone/Maven
Demo

15. New Template System
• Load Templates from Repository and/or Workspace
• Base Templates Updated for OSGi Release 6

16. Template Demo

17. Hash Dependencies
-buildpath: osgi.cmpn; version=hash; hash=292ecca5d8…
• Guaranteed repeatable builds.
• Repos can answer queries purely by hash.
• Safely consume from external repos.
• Hash + BSN validated after download.

18. Future Plans
• Moar Maven integration!
• Incremental bundle build in m2e?
• Clean up Repository Plugin API.
• Export to Docker?
• JSR 376 (Java Platform Module System) Support?
