Review Comment:
> i.e. enabling the remote cache is a deliberate act so if it then doesn't
work that should be an error not a warning.
In the situation where the user doesn't expect the remote cache to work,
e.g. working offline, they should disable it.
I don't think that's the intended scenario described by the author.
The remote cache can be working 100% correctly and still not contain the
requested items. In fact, this is 100% bound to happen, unless the cache is
magically warmed-up beforehand.
1. New project/branch/version/whatever so cache is empty.
2. Build starts
3. Cache extension cannot find cache item of Module X. <-- this is 100%
normal and expected behavior and shouldn't throw an error (or even a warming
i.m.h.o.), let alone a stack-trace.
4. Module X gets built
5. Module X output gets put into the cache
6. Next build starts, and now it can find cache item of Module X.
Having the logs filled with error/stack-traces for non-issues is
counterproductive. So I support any attempt at a more sane output and
error-handling.
