Very much needed, thanks for this!

[cjwirth]

This is definitely something we need!

In the meantime, is there some kind of workaround?

[cjwirth]

What I ended up doing is just forking all the repos that were failing (recurseively... 😞) and removed the Tests directory, and changing all the Package.swift files to point to my fork. Hopefully there's an easier way?

@cjwirth You can build and install swiftpm yourself with this patch in the meanwhile, that'd be easier I think. It'll be a while before this is accepted, merged and a snapshot is released

@cjwirth Actually there is a hacky way to do this, you'll probably want to hide this in a script/Makefile

1. Run swift build once, which will successfully pull the dependencies, but eventually fail bc of the above error
2. Recursively delete/rename all folders called Tests in Packages
3. Run swift build again, this time the modified Packages contents will allow for a clean compilation of all the dependencies.

This feels slightly better than having to fork all dependencies recursively.

This is probably the more correct way to do it, but unless want to try my hand at some development myself, I'd rather just use the snapshots .

Aah, this makes a lot of sense. This is exactly the kind of hacky workaround I was looking for, thanks!

Using a newer swift build is pretty easy: You can build SwiftPM with swift build and put it first in the path.

Rebased and solved conflicts due to #180

LGTM 👌

@swift-ci Please test

Can I merge this? 😬
