Re: plans for eclipse luna in debian

[Luca Vercelli <luca.vercelli.to@gmail.com>]

Here is a rules file to download sources.

Now, what about Tycho's dependency on Eclipse? If you want a more
"clean" solution, I could create another package "eclipse-bundles", with
the same sources of eclipse, that build and install just the few (100)
bundles required by Tycho compilation. This could create also related
maven artifacts.

Description: Buld Eclipse plugins with Maven
 Tycho is focused on a Maven-centric, manifest-first approach 
 to building Eclipse plug-ins, features, update sites, RCP applications 
 and OSGi bundles.
