go1.18を使ったときに、golangci-lintのtypecheckのエラーが出たり、go generateがこけた
//
golangci-lintのtypecheckのエラー
go.modで、go1.16が指定されているプロジェクトで、手元のgoのバージョンを1.18.2にしてgolangci-lintを実行したときに、今まで出ていなかったエラーが発生しました。こんな感じ
...net/http/httptest (-: could not load export data: no export data for "net/http/httptest") (typecheck)
"net/http/httptest"
^
k8sapiserver/k8sapiserver.go:23:13: could not import...load export data: no export data for "k8s.io/kubernetes/pkg/kubeapiserver/authorizer/modes") (typecheck)
authzmodes "k8s.io/kubernetes/pkg/kubeapiserver/authorizer/modes"
^...
...
go1.16.15やgo.17.10では、上記のエラーは発生していませんでした。
対処
golangci-lintのバージョンを最新に上げました。（ちょうど別件でgo.modに記載のバージョンも上げたので念のため記載しておきます。）
# go.mod - go 1.16 + go 1.17 - github.com/golangci/golangci-lint v1.41.1 + github.com/golangci/golangci-lint v1.46.2
上記の対応により、手元のgoバージョンgo1.18.2で、先のエラーは発生しなくなりました。
go generateがこけた
上記の続きで、go1.18.2を使ったときにgo generateを実行したときに以下のエラーが発生しました。
go generate ./...

go1.16.15を使用していたときは発生していませんでしたが、こちらgo1.18.2を使用し始めたときに発生するようになりました。
対処
ここにある２つのうちのどちらかで対処可能です。
例えば以下のように修正します。
- //go:generate mockgen -destination=./mock_$GOPACKAGE/pod.go . PodService + //go:generate mockgen --build_flags=--mod=mod -destination=./mock_$GOPACKAGE/pod.go . PodService
