dep init failed to convert github.com/boz/kail from govendor to dep

[dcheney-atlassian]

What version of Go (go version) and dep (git describe --tags) are you using?

% go version
go version devel +1a2ac46 Mon Aug 21 21:08:17 2017 +0000 linux/amd64

What dep command did you run?

% go get -d github.com/boz/kail
% cd $GOPATH/src/github.com/boz/tail
% govendor sync
% go build ./cmd/kail

# builds successfully

% dep init
% rm -rf vendor
% dep ensure
% go build ./cmd/kail

What did you expect to see?

./kail built correctly both times.

What did you see instead?

See above, looks like dep init didn't match the exact revisions from govendor

[darkowlzz]

@dcheney-atlassian thanks for trying dep on an existing project, but we don't support govendor conversion yet 😞. There's a WIP PR #815 . Hopefully this issue would get solved soon 🙂.

[gianarb]

Hello @darkowlzz the PR #815 is merged. I tried the flow described above on one of my projects and it is failing for me too.

[darkowlzz]

@gianarb can you provide some more information about the failure? Import logs or your observations.

[sdboyer]

@gianarb actually - could you open a new issue with more details? the reasons why these conversions get things wrong can be complex and nuanced, and it's best to track each failure case separately.

wrt the original issue here, this is the error i now get:

$ go get github.com/boz/kail
$ cd $GOPATH/src/github.com/boz/kail
$ dep init -v

init failed: unable to prepare an initial manifest and lock for the solver: Cannot determine the project root for appengine: "appengine" is not a valid import path

[carolynvs]

Closing as the original issue, not supporting govendor during init, has been resolved.

@gianarb The govendor config looks incorrect because it contains an invalid path "appengine". If you correct the config and init continues to fail, please open another issue and we can figure it out.

[sdboyer]

that path was, at one time, valid. I know we had special handling for appengine at one point, though I don't immediately recall how much of it remains.

[carolynvs]

Ah okay I didn't read past this part of the appengine doc before thinking it was bad config:

This repository supports the Go runtime on App Engine standard. It provides APIs for interacting with App Engine services. Its canonical import path is google.golang.org/appengine.

Further down they provide instructions to get off their legacy appengine import style:
