Artifacts don't download after instantiating

I don’t understand why an artifact specified in the Artifacts.toml file doesn’t become available after instantiating an environment:

shell> ls
Artifacts.toml  Manifest.toml  Project.toml

shell> cat Artifacts.toml
# a simple Artifacts.toml file
git-tree-sha1 = "43563e7631a7eafae1f9f8d9d332e3de44ad7239"

    url = ""
    sha256 = "e65d2f13f2085f2c279830e863292312a72930fee5ba3c792b14c33ce5c5cc58"

(name) pkg> instantiate # here I thought the artifact would get "installed"

julia> using Artifacts

julia> artifact"socrates"
ERROR: Artifact "socrates" was not installed correctly. Try `using Pkg; Pkg.instantiate()` to re-install all missing resources.

Note, this is not used in a package, but in a project that is not a package.

Literally using ArtifactUtils solved this :stuck_out_tongue:
