     or pseudo version of a module, or a directory with a go.mod file.

     a build command such as go build, go list, or go test. The build list is
     determined from the main module's go.mod file and go.mod files in
     transitively required modules using minimal version selection. The build
     list contains versions for all modules in the module graph, not just those
     relevant to a specific command.
