What did you do?

Trying the new go modules.
Currently, the repo uses the dep and I want to move from dep to go modules.

Steps followed to move to go modules from dep (As described in https://github.com/golang/go/wiki/Modules):

  1. In the project root directory create the mod file go.mod: go mod init (This will read from the Gopkg.lock file for all the dependency information)
  2. Build the module. This will create a go.sum file in the root directory: go build ./...
  3. Test the module: go test ./...

It builds fine, but when I do go test ./... I see this error.

$ go test ./...

when I do 'go test all' I see this error:

What did you expect to see?

I expected the transition from dep to go mod with ease.

What did you see instead?

Errors !

The first error message says import path cannot be absolute path. Does your code have an import statement that uses an absolute path?

The second error message seems to be accurate. It says cannot find module providing package github.com/pierrec/lz4/v2/internal/xxh32. If we look at the latest v2 tag for that repository (v2.0.7), we find that it declares its module to be github.com/pierrec/lz4 (note the lack of /v2).

See also pierrec/lz4#33.

The first error message says import path cannot be absolute path. Does your code have an import statement that uses an absolute path?

I am not aware of any absolute paths in the import statements other than "github.com/...". Basically, all the import paths I see starts with "github.com/..." or a similar github private repo. I have "sync", "time", "container/list" but these are golang packages.

May be it is complaining about the absolute path in some dependency which I use ?

Possibly. Can you attach a code sample and exact commands to reproduce the error?

So, while initiating the mod I was giving an absolute path for the module like 'go mod init /user/temp' this was the cause of the first error!

Now, when I change the module path to something else like 'go mod init user/temp' it works fine.
Can you please direct me to some resources where I can learn how exactly the go modules works internally.

But, if I do 'go test all' I still see this error which is expected as you mentioned earlier.

The v2 change has been reverted for that repo - pierrec/lz4@bb6bfd1. You can remove that. The repo README is out of date.

Please see this https://golang.org/cmd/go/#hdr-Module_maintenance for more info.

It appears that all of the errors are now accounted for. Is there anything more to do?
