Cannot use v2.0.0-preview.5 with Go modules

[F21]

Please fill out the sections below to help us address your issue.

Version of AWS SDK for Go?

v2.0.0-preview.5

Version of Go (go version)?

Go 1.11 Linux x64

What issue did you see?

v2.0.0 includes a go.mod file, but the import path in the go.mod file is github.com/aws/aws-sdk-go-v2. This means that Go modules is not able to import the library because the tag is v2, but the path in the go.mod file is not v2. Go modules will only import v2.0.0-preview.4 due to the import path in go.mod being wrong.

To fix this, the import path in go.mod should be updated to github.com/aws/aws-sdk-go-v2/v2 and all references to github.com/aws/aws-sdk-go-v2 within the library should also be updated to ``github.com/aws/aws-sdk-go-v2/v2`.

The tags should never have been v2, as we changed the repository between SDK "v1" and "v2", so a v1 of github.com/aws/aws-sdk-go-v2 has never existed.

A cleaner but build-breaking approach would be to delete all the existing tags and start over with v0 or v1.

Thanks for reporting this issue. We'd created the v2 SDK's repo prior to the go module proposal, and this is why a combination of v2 tagging along with the repo name being aws-sdk-go-v2.

To workaround this issue temporarily you can do:

go get github.com/aws/aws-sdk-go-v2@v2.0.0-preview.5

A aws-sdk-go-v2/v2 isn't a pattern we'd like to use because of its verboseness, and would prefer to either have the v1 and v2 SDK in the same repo (aws-sdk-go/v2) (This wasn't viable until go modules were introduced), or keep the v2 SDK in its own repo. Though we'd probably keep the v2 SDK in its own repo. If we keep the v2 SDK in its own repository (aws-sdk-go-v2) then the SDK should switch to using v0 for its preview build tags and switch to v1 once GA released. I think we'll need to delete the v2 build tags. I'm not sure how a v0 and v2 tag will work with go modules. We'll need to experiment with this.

Thanks for letting us know about the issue with the SDK and Go Models. During the SDK's preview we'll us v0.<x>.<y> release tags. This will allow the v2 SDK to work correctly with Go Models. We'll continue this until the SDK's General Availability (GA) release.
