hi
i also encounter the same issue
while trying to generate the mock file
project structure :
C:/.../parent/internal/handler/handler.go
C:/.../parent/internal/mocks/mock_handler.go

currently, I generate/execute from a command prompt on windows, and I am on the parent folder
go mock version =
mockgen --version
v1.6.0

set GOHOSTARCH=amd64
set GOHOSTOS=windows
set GO111MODULE=on
set GOARCH=amd64
set GOVERSION=go1.18
set GOOS=windows
set GOSUMDB=off
set GOEXE=.exe

i have try to add _ "github.com/golang/mock/mockgen/model"
and generated it using go mod vendor
i already have go mod file generated from go mod init as well

mockgen -source=internal/handler/handler.go -destination=internal/mocks/mock_handler.go -package=mocks --build_flags=--mod=mod
2022/07/19 16:35:41 Loading input failed: failed parsing source file internal/handler/handler: open internal/handler/handler: The system cannot find the path specified.

before this i did this step

1. go install github.com/golang/mock/mockgen@v1.6.0
2. go get github.com/golang/mock/mockgen/model
3. mockgen -source=internal/handler/handler.go -destination=internal/mocks/mock_handler.go -package=mocks

i can only generate the file
if i tell exactly where the file is
for example :
mockgen -source=C:/go/parent/internal/handler/handler.go -destination=internal/mocks/mock_handler.go -package=mocks

but file that was generated, only include the package without go extention
// Code generated by MockGen. DO NOT EDIT.
// Source: C:/go/parent/internal/handler/handler.go

// Package mock_handler is a generated GoMock package.
package mock_handler

I am unable to reproduce this. Can you please create a small sample repo to reproduce this? I made this folder structure and it generated to mock.
