Hydra: Make it possible for travis-ci to build forked repos

[emilva]

I am having a issue where my forked repo is not building:
go install github.com/ory-am/hydra can't load package: package github.com/ory-am/hydra: cannot find package "github.com/ory-am/hydra" in any of: /home/travis/.gimme/versions/go1.5.linux.amd64/src/github.com/ory-am/hydra (from $GOROOT) /home/travis/gopath/src/github.com/ory-am/hydra (from $GOPATH)
https://travis-ci.org/emilva/hydra/jobs/166870439#L454

The reason for this error is that any forked repo slug /github-username/hydra will never match /ory-am/hydra.

Suggested fix is to re-run line 247-250 https://travis-ci.org/emilva/hydra/jobs/166870439#L247
with ory-am/hydra instead of the forked repo slug

This can probably easily be solved by replacing go install github.com/ory-am/hydra with go install .

[emilva]

No, that will not work, as there are other packages inside ory-am/hydra that the install depends on. When doing that we get this warning:
`[WARN] The name listed in the config file (github.com/ory-am/hydra) does not match the current location (github.com/emilva/hydra)``

and subsequently a failure:
main.go:7:2: cannot find package "github.com/ory-am/hydra/cmd" in any of: /home/travis/gopath/src/github.com/emilva/hydra/vendor/github.com/ory-am/hydra/cmd (vendor tree) /home/travis/.gimme/versions/go1.5.linux.amd64/src/github.com/ory-am/hydra/cmd (from $GOROOT) /home/travis/gopath/src/github.com/ory-am/hydra/cmd (from $GOPATH) The command "go install ." failed and exited with 1 during .
https://travis-ci.org/emilva/hydra/jobs/166904313#L450

Ah yes, I forgot about that part. I'm not sure if this is what you suggested, but maybe there is a way to tell travis to put the source code in src/github.com/ory-am/hydra instead?

[emilva]

Yupp. Tried something like that in 👉 https://github.com/emilva/hydra/commit/26a59b0c9c988d5ee7646ff31f2dbdf2bbd7aa74

however, now it fails further down in some test I think https://travis-ci.org/emilva/hydra/jobs/166904073#L883

[emilva]

Found a related fix for it here, but have not yet made it work in this repo.

[aeneasr]

Looks like it's working almost! The culprit is now coveralls, which is trying to push the changes to coveralls.io but since the fork isn't registered there, this fails: https://travis-ci.org/emilva/hydra/jobs/166904073#L631

One idea might be to move this to after_success:

By the way, the way cfssl is doing it (https://github.com/cloudflare/cfssl/blob/master/.travis.yml#L20-L27) looks really cool, because it's just 2 lines of code without rsync dependency :)

[emilva]

Yupp, I will revisit it and take a look at it later!

[emilva]

Moved it and now the build is green! However, I still see this strange error message at the end tho:
https://travis-ci.org/emilva/hydra/jobs/167926554#L884

is it intended?

[emilva]

Still having some issues with just a simple create dir and move commands.
It works for go1.7 but not for the two other versions. Any idea why?

Failed build:
https://travis-ci.org/emilva/hydra/jobs/167935209#L270

Successful:
https://travis-ci.org/emilva/hydra/jobs/167935211

[aeneasr]

Yes, Hydra builds only on Go 1.7 from now on

[aeneasr]

at least in the 0.6.0 branch

It may be simpler to set the go_import_path explicitly in .travis.yml. See https://docs.travis-ci.com/user/languages/go#Go-Import-Path
