I think this change was introduced here https://go-review.googlesource.com/#/c/114317/ and here golang/tools@9a70f1f

Our automated build system is now also breaking on import

+ go get -u github.com/golang/lint/golint
# golang.org/x/tools/go/internal/gcimporter
src/golang.org/x/tools/go/internal/gcimporter/bimport.go:541:8: undefined: types.NewInterface2
src/golang.org/x/tools/go/internal/gcimporter/iimport.go:540:10: undefined: types.NewInterface2

Confirmed. /cc @griesemer.

I'm also getting a failure on this

$ go get github.com/golang/lint/golint
# golang.org/x/tools/go/internal/gcimporter
../../../golang.org/x/tools/go/internal/gcimporter/bimport.go:541:8: undefined: types.NewInterface2
../../../golang.org/x/tools/go/internal/gcimporter/iimport.go:540:10: undefined: types.NewInterface2

Given that a number of us are coming across the same problem, let's be nice to the maintainers and not post confirmations unless we have constructive info that'll help them put out the fire 😄. Also, it's great to see so many of us are using golint!

Same issue here. Any ETA on the fix?

See golang/lint#402.

All: Apologies for all this.

Post-mortem: Late last night (with emphasis on "late") I created a larger CL in an attempt to finally update x/tools with all the latest fixes and changes that we've made to the various importers in the std lib. This also included fixes to go/types and new tests. The CL was approved and passed all (1.11) tests and I submitted it somewhat in a rush this morning while running out of the door, not thinking abut pre-1.11 builds. As we all saw, the non-1.11 builds failed quickly, and with it tools such as lint that depend on go/types. It was "obvious" what needed to be fixed (the go/types.NewInterface2 call is missing pre-1.11). While submitting that fix, I missed a couple of places (sigh), and also the fact that Interface.EmbeddedType was new as well. Finally, some of the new tests don't pass at all pre-1.11 due to larger fixes in go/types. I've split up the code into version-tagged files and I believe it works now. The primary reason for having these problems in the first place (and not fixing it all with a single CL) is that I relied on the builders to test non-1.11 versions for "expediency" (I hoped to get around installing a pre-1.11 setup on my new laptop while on the go.) Lesson (re-)learned.

I still see a build failure for 1.9 but it is unrelated to the importers.

Please confirm this is now working again and close if so. Thanks.

golang/lint#402 has been confirmed as fixed; this is the same issue. Closing.
