go.mod has post-v0 module path "git.example.com/owner/repo/v3" at revision ...?


My coworker pushed a tag v3.0.1 before updating go.mod to have /v3 suffix (https://github.com/golang/go/wiki/Modules#releasing-modules-v2-or-higher). I have updated module path (go.mod) and all import paths (*.go) to fix it, tagged as v3.0.2.

Now the problem is:

go get -v git.example.com/owner/[email protected]
go: finding git.example.com/owner/repo v3.0.2
go: git.example.com/owner/[email protected]: go.mod has post-v0 module path "git.example.com/owner/repo/v3" at revision 
d85c4f69ad17

Found this: go build keeps complaining that: go.mod has post-v0 module path

So, I deleted both v3.0.0 and v3.0.1 tags, pointed it to the latest commit, re-pushed but the problem still stand.

I noticed that go.mod still refered to the old version as an indirect dependency:

require (
    git.example.com/owner.repo v0.1.2 // indirect

Even if I changed it to /v3 v3.0.2 it will be restored to v0.1.12 automatically.

Why?

Did I miss something?

rm go.*
go mod init git.example.com/dependent/project
go mod tidy

and go.mod is updated correctly now:

require (
-       git.example.com/owner/repo v0.1.2
+       git.example.com/owner/repo/v3 v3.0.2

but go get -v git.example.com/owner/[email protected] still returned the error:

go: finding git.example.com/owner/repo v3.0.2
go: git.example.com/owner/[email protected]: go.mod has post-v0 module path "git.example.com/owner/repo/v3" at revision 
d85c4f69ad17

(d85c4f69ad17 is the latest commit in master)

I noticed that there are both v0.1.2 and v3.0.2 in go.sum:

git.example.com/owner/repo v0.1.2 h1:mCGJEmyrFDTCGkRfUIORpqdrNkSONQ6K+AcTNgxqveY=
git.example.com/owner/repo v0.1.2/go.mod h1:FfUKnyPrARCtAXQZ3BQVJI7h2eJ0UpQBMLg4bNs4Kdc=
git.example.com/owner/repo/v3 v3.0.2 h1:mJtDKLeiP8vMRSZo08i/k/KDbIoZTlKW2aWu7DUBvMM=
git.example.com/owner/repo/v3 v3.0.2/go.mod h1:64LE0ts0Lk9InIQyhPYGmnxs6LZIl6H4Iorl1EXfqxo=

Solution

  • Please pay attention to my go get command:

    go get -v git.example.com/owner/[email protected]
    

    It should be:

    go get -v git.example.com/owner/repo/[email protected]
