[tycho-user] Attach source for eclipse-plugin

[motes motes <mort.motes@xxxxxxxxx>]

I build and eclipse-repository with a feature containing some of my
own eclipse plugins, A,B and C.

I copy this repository to an internal server and reference it on a
target platform for another project X. Now when I debug my code from
project X that has dependencies on A, B and C I would like to see the
source. But that requires that I attach the source when I build the
plugins/feature/repository I guess. How is that possible using tycho
0.14 - should it be specified in the plugin, feature or repository?
