go_unittest cannot depend on non go_library() target

I am trying to build a golang unittest that depends on a non go_library target. I need the side effects of the target to run. I see the error:

BUILD FAILED: //:generated_asset (needed for //:main#compile,darwin_amd64) is not an instance of go_library!

Is this just a missing feature of the golang support in buck? Is there another way to create a manual dependency between a golang targets and something else that does not imply the golang target should link the targeted thing as if it were a go library?

Note, I have create a sample project demonstrating the issue: https://github.com/lloyd/buckissue

It can but only for go_test. Buck will symlink the output to current directory while running buck test, for example:

...
go_test_link_tree @ buck-out/gen/buckissue/__test_main_test_output__/working_dir
go test
...

so the asset can be referenced within current directory. However this is only during buck test execution, so if you try to run:

./buck-out/gen/buckissue/main_test#test-main/main_test -test.v

it won’t find the file.

Let’s say we add “resources” to go_binary then we could mimic the go_test behavior with:

$ buck run ... 

which would change the working directory
