listing deps for package %s failed

Error message

listing deps for package %s failed

What it means

gopathDependencyPackageInfo wraps the exit error of the spawned 'go list' command with 'listing deps for package %s failed'. The go toolchain itself exited non-zero while computing the dependency list, so dependency walking for the package fails.

Solutions

1. Read the wrapped go stderr in the error to see go's own message
2. Fix compile/import errors in the chaincode package ('go build ./...')
3. Align the Go toolchain version used by the peer builder with the chaincode requirements
4. Ensure the package directory is a valid Go package with a .go file at the expected path

Example fix

// chaincode with broken import
import "github.com/me/lib"  // not in go.mod
// after
$ go get github.com/me/lib && go mod vendor

cmd := exec.Command("go", "list", "./...")
if out, err := cmd.CombinedOutput(); err != nil {
  return fmt.Errorf("go list failed: %v: %s", err, out)
}

When it happens

Trigger: cmd.Wait() returns non-zero after 'go list -deps -json ...' runs on the chaincode package — compile errors in scanned deps, bad GOFLAGS/GO111MODULE env, or go binary issues in the peer environment.

Common situations: Chaincode source does not compile (syntax/type errors) causing go list to fail; incompatible Go version in the peer vs chaincode; GO111MODULE/go env conflicts in the builder container.
