(Re)setup eclipse for ESH/OH development (oomph/eclipse installer)

Hello all,

I know how to successfully setup an eclipse environment with the eclipse-installer. But how can I change that initial setup (for example from eclipse smarthome core development to ESH core and OH2 binding) with a minimum of reloading online resources?

Reinstalling eclipse, cloning the (already cloned) gits and loading all necessary bundles takes really long (multiple hours) on my current connection, so I’m looking for a way to “execute” the *.setup files that a part of the repositories. Is there a way?

Thanks, David
