Go - Tips - generate gomock

#go #tips

I got the following error today, but I was able to generate it successfully after deleting the existing mock file.

% mockgen -source　./internal/app/usecase/xxx/repository.go -destination ./internal/app/usecase/xxx/repository_mock.go -package xxx
-: found packages xxx (repository.go) and mock_updateproteinevent (repository_mock.go) in /Users/xxx/go/src/proteinreminder/internal/app/usecase/xxx
