Source mode fails with embedded interfaces

[amatoenot]

Here are my test files:

github.com/anyuser/test/test1.go:

package test

type A interface {
	Method1()
}

github.com/anyuser/test/test2.go:

package test

type B interface {
	A
}

Here's generation:

mockgen -source test2.go -destination test2_mocks.go -package test -aux_files test=test1.go

Error result:

Loading input failed: test2.go:4:2: unknown embedded interface A

Hi Sergey,

The command line for aux_files needs the full package name:

mockgen -source test2.go -destination test2_mocks.go -package test -aux_files=github.com/anyuser/test=test1.go

Also, you mentioned in #85 that you used reflect as a fallback. Please consider reflect mode as the first option to try and use source mode only if it can't work for some reason.

Finally, I opened #181 to look into eliminating the need for aux_files altogether.

Hi @balshetzer I encountered the same issue. Here are my files.

github.com/project/handler/init.go

package handler

type Handler interface {
	adminHandler
}

github.com/project/handler/admin.go

package handler

type adminHandler interface {
	Method()
}

Here's generation

mockgen -source init.go -package handler -aux_files=github.com/project/handler=admin.go  -destination mock_handler.go

Here's the output

Loading input failed: init.go:88:2: unknown embedded interface adminHandler

i don't know what's wrong with my command. can you help?
