Stack dependencies with subdirs are not supported #60
Description
I have the following dependencies in my stack.yaml:
- location:
git: git@github.com:arbor/antiope.git
commit: ba073b0cd3847f6549960ecdd321259581582146
subdirs:
- antiope-core
- antiope-s3
extra-dep: true
But stackage2nix doesn't seem to like it:
error: unable to download 'git@github.com:arbor/antiope.git': URL using bad/illegal format or missing URL (3)

The repository is public (https://github.com/arbor/antiope), and I don't understand why it initially says
error: unable to download 'git@github.com:arbor/antiope.git': URL using bad/illegal format or missing URL (3)
It seems that it can download the repo successfully anyway, but then it doesn't recognise that the actual packages are sitting in subfolders.
Both Stack and Nix allow subfolders, so perhaps something can be done on stackage2nix side to support them too.
