What is it?

Slingshot is an Über Repository for Eclipse Projects

• An aggregate repository
  • Like the simultaneous release repository
  • But without the rigours (or quality assurances)
• A means for projects to extend their reach
• Manifests as a p2 and Maven repository
• Target Audience
  • Developers/Committers
  • Adopters
  • Not intended to be included in packages
  • Not for end-users

When

Go live on June 23/2010 is planned.

• May 2010?
  • Orbit bundles aggregated
  • Other test projects?

• Limited rollout in June?
  • Scale to ~10 projects (+Orbit) aggregated?

Aggregator

Slingshot is a p2 repository aggregator. It gathers the contributions from multiple project repositories, and combines them into a single repository that is accessible as both a p2 and Maven repository. Only code that has resolvable dependencies is included in the aggregate repository. Unresolved dependencies are reported back to the project.

• Includes only integration and release builds
• Copies artefacts into a copy repository;
• Retains all artefacts

Opt in

To participate in Slingshot, a project must provide a " contribution" file (which uses the same format as the release train). This file is typically stored in the project's website CVS. A pointer to this file is provided via the portal using the Project's "slingshotconfigurationurl" attribute (this is a single absolute URL).

Repository

• Links to simultaneous release repository
• Retains all artifacts
  • Restricted to milestones and release builds only
  • Facilitates reproduceable builds
• Categorizes based on project structure
• Automated
  • We don't chase down your dependencies
  • That's your job!

Benefits

• Easier for developers to get the project bits
• Avenue for projects to gain exposure
• Not indended for end users
  • No quality assurances
