Review comment:
I'd rather keep it consistent with Lucene, if you don't mind. Not a
native speaker but is something wrong with the "dummy"? I am aware of other
senses but this literal definition suits me just fine in this context "an
object designed to resemble and serve as a substitute for the real or usual
one."?

Review comment:
It doesn't have to be. It can be plain Java API. We're not being fancy
with the lazy API here so I don't think we need to make things complicated?
There is a semantic difference between Input and InputFile - this was a bug.

Review comment:
I wondered about this too, but in the end opted for simplicity. This
initial generated settings file is meant to provide the defaults and pointers
about where other things can be tweaked. But it is meant to be tweaked to your
(the developer's) needs and I know some folks are doing just that. Manipulating
their changes would only create more headaches. You can always wipe this file
and let it regenerate if you want it refreshed entirely.
I think these days you could also use init scripts to set up your local Solr
builds completely independently from the repository structure [1]. I haven't
toyed with this though.

Review comment:
I think you're familiar with it, you just don't know it. :) I recall I
head-scratched over the very same thing... It's a gstring (lazily evaluated
string) with a snippet of gradle code which happens to be a parameterless
closure. The jar plugin is actually better now and supports lazy providers...
So this could be modified entirely. I just copied the solution that worked in
Lucene.

This doc explains the difference, btw.
