Report #73482

[bug\_fix] go: github.com/myorg/[email protected]: reading github.com/myorg/private-repo/go.mod at revision v0.0.0: unknown revision v0.0.0

Set the GOPRIVATE environment variable to include the private repository path \(e.g., export GOPRIVATE=github.com/myorg/\*\). This tells the Go toolchain to bypass the public proxy and checksum database and fetch the module directly from the source repository.

Journey Context:
A developer adds a private internal library as a dependency and runs go mod tidy. It fails with an unknown revision or 410 Gone error. The developer initially goes down a rabbit hole of configuring Git SSH keys and .gitconfig, thinking it's an authentication issue. However, the real problem is that the Go toolchain defaults to fetching modules via the public proxy \(proxy.golang.org\). The proxy doesn't have the private repo and returns an error. Setting GOPRIVATE fixes this by instructing the go command to bypass the proxy and fetch directly from the VCS source, where the Git credentials actually apply.

environment: Go 1.13\+, CI/CD pipelines, private Git repositories \(GitHub Enterprise, GitLab self-hosted\) · tags: goprivate proxy authentication module-fetch · source: swarm · provenance: https://go.dev/ref/mod\#private-modules
