• Go: 1.12.x

Steps to Reproduce
Steps to reproduce the behavior:

3. See an error

Actual behavior
An error occurred during Travis run:
The command "go get github.com/vektra/mockery/.../" failed and exited with 1 during .

Expected behavior
Travis run ends successfully

Additional context
In vektra/mockery repository there is information, that v1, which is currently used, is outdated and no longer supported.
V2 has a different commands syntax (and maybe this is not the only difference compared to v1)

There is a v1 version on "releases" page on vektra/mockery repository. But is it possible to download it via "go get ..."?
