  • SR-4124 Dependency resolution error for unsatisfiable dependencies due to tools version should say why

Issue Description:

This example repository shows a regression in SPM between Swift 4.2.1 and Swift 5. In particular, running "swift package resolve" works fine with Swift 4.2.1, but gets stuck with Swift 5.

Comment by Pierpaolo Frasa (JIRA)

The problem seems related to the CSwiftV dependency, which does not specify a swift-tools-version, therefore defaulting to 3.0. However, this specific error message is only displayed when trying to build that specific repository itself. When it's a dependency, it either just hangs, or (when it's the sole dependency), it shows:

Updating https://github.com/Daniel1of1/CSwiftV
error: dependency graph is unresolvable; found these conflicting requirements:

Dependencies:
https://github.com/Daniel1of1/CSwiftV @ 0.0.7

Therefore, this is an issue of bad diagnostics, not strictly a bug in functionality.

Long standing issue. We hope to resolve this with PubGrub resolver.
