go build can't find a revision

Question

I developed a repo on computer A and created a go.mod/go.sum that I checked in.

I pull that repo with the go.mod/go.sum files on computer B, but when I try to build the program, the module constraints can't be satisfied.

$ go build
go: finding github.ibm.com/kms/key-protect-client v0.1.5
go: finding golang.org/x/tools v0.0.0-20180221164845-07fd8470d635
go: github.ibm.com/kms/[email protected]: unknown revision v0.1.5
go: error loading module requirements

The repo that is failing is a private repo, and for some reason it doesn't get downloaded to the module cache. On another computer, the dependencies are downloaded and the build succeeds. I am building another private repo in that same domain, so I know that my github credentials give me access to these repos. But for some reason, the go module system can't get to the dependent repo.

I cannot find more information how to debug this.

Solution 1

Problem is related to cmd/go not being aware of git identities and assuming there is only one articulated in the .gitconfig file.

Work-around: have a set of git identities ready to replace global .gitconfig when you need to work with that git identity and are dealing with cmd/go tools that update the module file.

Possible solutions for golang unknown revision if you are using private repository:

1. git config --global url."ssh://git@yourserver".insteadOf "https://yourserver"

2. Check your git repository permissions

Solution 3

I had the same problem, please, visit the link .

Make sure you have set GO111MODULES

go env -w GO111MODULE=on

Make sure your git configuration is appropriate for private repositories

git config --global url."ssh://[email protected]:acme-corporation".insteadOf "https://github.com/acme-corporation"

Make sure to create a personal access token if using 2FA

git config --global url."https://:[email protected]:acme-corporation".insteadOf "https://github.com/acme-corporation"

in my case after setting:

• ~/.gitconfig
• ~/.bashrc

I had to do the same with the ~ / .netrc file:

machine gitlab.url.com
    login <gitlab username>
    password <GITLAB_TOKEN>

Solution 4

In case getting

"Error": "unknown revision ..."

or

"Error": "invalid version ..."

Make sure that you did not specify hash of PR (pull request). Even a merged PR might be wrong.

Look for the commit hash in the github repo under /commits, but not under /pulls.

See more info here: golang/go#31191 explicitly filters out these kind of commits.

Solution 5

Just in case, did you add "github.ibm.com/kms" to your environment variable GOPRIVATE on computer B? I've had this error occur to me due to exactly this reason.
