Expected root cause […] to almost satisfy the current partial solution

[Frizlab]

Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?

• Confirmed reproduction steps with SwiftPM CLI.

Description

I got the following internal error while running swift package resolve:

/* To find a valid test for Xcode detection, we sneakily inserted the following code in the products definition, just before the return:
 *    for (key, val) in ProcessInfo.processInfo.environment {
 *       res.append(.executable(name: key, targets: [val]))
 *    }
 * This generated a bunch of errors about invalid targets for the executable products,
 *  w/ the name of the executable being the key of the environment value and the target name its value.
 * From this we devised a check which was likely to be true in Xcode and unlikely to be true anywhere else.
 *
 * When tested, the actual value of the environment key we chose was `com.apple.dt.Xcode`.
 * We did not test directly for this in the check as _maybe_ some versions of Xcode have a different bundle ID (I don’t think so but we never know…). */

Expected behavior

The graph should resolve.

Actual behavior

We get an internal error.

Steps to reproduce

Create a project with the given Package.swift and try to resolve it..

Note: togever-api-model depends on generic-json from: "3.0.0".

I suspect this is the root cause of the issue: my package depends on a beta version of generic-json and on a package (togever-api-model) which depends on a non-beta version of generic-json.
It should work, but we get an internal error instead.

I did not try reducing the problem to this simpler use-case but I did get the issue when I updated the requirements for generic-json in my package.
