unable to find sampleconfig directory on GOPATH

Error message

unable to find sampleconfig directory on GOPATH

What it means

gopathDevConfigDir scanned every GOPATH entry for src/github.com/hyperledger/fabric/sampleconfig and found none. This dev-only helper locates the in-tree sample configuration; absence means the source tree is not on GOPATH.

Solutions

  1. Use Go module mode so gomodDevConfigDir resolves the sampleconfig dir next to go.mod
  2. Clone the fabric source into a GOPATH workspace
  3. Copy sampleconfig manually and point the test at it

Strategy: fallback
