If both a "versioned" and "non-versioned" version of a dependency exists in vendor.conf, the "longest" path should be cloned last, otherwise the versioned dependency may be deleted when cloning its non-versioned variant. For example, with the following vendor.conf: github.com/coreos/go-systemd/v22 v22.0.0 github.com/coreos/go-systemd v17 Running vndr would; 1. recursively delete "vendor/src/github.com/coreos/go-systemd/v22: 2. start cloning "github.com/coreos/go-systemd/v22" 3. recursively delete "vendor/src/github.com/coreos/go-systemd" 4. start cloning "github.com/coreos/go-systemd" This would lead to a conflicting situation; step 3. will remove the dependency that was previously cloned (or in the process of being cloned). This patch sorts the dependencies by import-path, cloning the shortest import paths first, which should prevent the race condition. Signed-off-by: Sebastiaan van Stijn <[email protected]>

shortest import paths first, which should prevent the race condition.
This should address the issue seen in #40873 (comment)
