Tycho/Additional Tools

The Tycho project provides additional tools that may be useful when working with Tycho.

tycho-p2-extras-plugin

The mirror goal of the tycho-p2-extras-plugin copies installable units (plus their corresponding artifacts) from one or more p2 repositories into the build directory. This goal is available since version 0.13.0.

Example usage:

Mirror the org.eclipse.rcp feature from the Indigo p2 repository to target/repository. Filter the platfrom-specific fragments to only include linux/gtk/x86_64 os/ws/arch.
