error: the package has an unsupported layout, unexpected source file(s) found: /Users/maximveksler/Project/Org/Collection/Sources/main.swift

The most recent change I've done is add the Sources/extensions/Jay.swift,
now I'm unable to build the project.

No idea what could have gone wrong, feedback?

➜ Collection git:(master) ✗ find Sources
Sources
Sources/extensions
Sources/extensions/Jay.swift
Sources/main.swift

➜ Collection git:(master) ✗ cat Package.swift
import PackageDescription

let package = Package(
    name: "Collection",
    dependencies: [
      .Package(url: "https://github.com/GraphQLSwift/GraphQL.git",
majorVersion: 0),
      .Package(url: "https://github.com/czechboy0/Jay.git", majorVersion: 1)
    ]
)

➜ Collection git:(master) ✗ swift build
error: the package has an unsupported layout, unexpected source file(s)

fix: move the file(s) inside a module

If you want one module with both sources but some in a subdirectory, you need to write it as:

Sources/Collection/main.swift
Sources/Collection/extensions/Jay.swift

If you want two modules then you need to lay this out as:
Sources/extensions/Jay.swift
and
Sources/Collection/main.swift

We know this UX is not very good and are debating how to best resolve this...

Thanks Daniel,

Few comments:

Error message is very confusing and doesn't provide a hint to what went
wrong.

I'd suggest to solve this by assuming default for 1 module, and if
main.swift is present then building an executable. Allowing multiple
modules in same package I think should be discouraged, because at least
intuitively for me a Package translate to a Module in a 1:1 relation.

It's also import the inconsistency between Xcode project produced by swift
package generate-xcodeproj which is able to build the mentioned layout and
the command line swift build that fails.

Thanks for the help, mv'ing the sources into a a "Collection" directory in
Sources solved the issue.
