I have a registered package [Preconditioners.jl](https://github.com/mohamed82008/Preconditioners.jl) which depends on an unregistered one [IncompleteSelectedInversion.jl](https://github.com/ettersi/IncompleteSelectedInversion.jl). And I want to have this dependency in a v0.7 compatible way.

Previously when I asked the same question a bit over one year ago [How to add unregistered packages to REQUIRE?](https://discourse.julialang.org/t/how-to-add-unregistered-packages-to-require/4737) I got the answer to either wait for `Pkg3` or put the installation instruction of the unregistered package into the `build.jl` file of the registered one. This works in v0.6 but not in v0.7. It downloaded the unregistered package in the `dev` folder since I used `Pkg.clone` in the build.jl file, but running `using Preconditioners` gives the following error, which shows that `Pkg3` doesn’t approve of this workaround, so what’s the alternative?

```julia
ERROR: LoadError: ArgumentError: Package Preconditioners does not have IncompleteSelectedInversion in its dependencies:
 - If you have Preconditioners checked out for development and have
   added IncompleteSelectedInversion as a dependency but haven't updated your primary
   environment's manifest file, try `Pkg.resolve()`.
 - Otherwise you may need to report an issue with Preconditioners.

```

And of course `Pkg.resolve()` doesn’t help.

What if you add `IncompleteSelectedInversion` to your REQUIRE file?

It is not registered though so it wouldn’t know what to download?

If you make it available by e.g. `dev` or `add url` then it doesn’t have to download it.

Sure but I mean for others who want to add Preconditioners, how can they get IncompleteSelectedInversion without a fuss? Oh you mean I keep the `Pkg.clone` and add it to REQUIRE?

There should not be a registered package that depends on un unregistered one as far as I understand. Why don’t you register the other package too?

Apparently the other one is unmaintained and MIT licensed so I am absorbing it into my package for ease of maintenance. The author didn’t want to register it.
