What did you do?

1. set GO111MODULE=on
2. change current directory to a module
3. run go list -e -json /Users/matloob/Desktop (or list any existing directory outside of any module)

What did you expect to see?

exit status of 0, empty stderr, and a "Fake" package with errors set to a message saying the directory is outside any modules.

What did you see instead?

exit status of 1 and stderr of "go: directory ../Desktop outside available modules\n"

[gopherbot]

Change https://golang.org/cl/195065 mentions this issue: go/packages: suppress go list -e error when directory outside modules

[bcmills]

Possibly related: #29280, #26909.

Another variation of this error:

$ go list ../...
go: pattern ../... refers to dir /tmp/foo, outside module root /tmp/foo/b

[dominikh]

I believe this is fixed in Go 1.15:

$ go version
go version go1.15beta1 linux/amd64
$ go list -json -e ../...
{
	"ImportPath": "../...",
	"Match": [
		"../..."
	],
	"Incomplete": true,
	"Error": {
		"ImportStack": [],
		"Pos": "",
		"Err": "pattern ../...: directory prefix .. outside available modules"
	}
}
$ echo $?
0
$ go list -e -json /home/dominikh/prj/src/sandbox/bar
{
	"ImportPath": "/home/dominikh/prj/src/sandbox/bar",
	"Match": [
		"/home/dominikh/prj/src/sandbox/bar"
	],
	"Incomplete": true,
	"Error": {
		"ImportStack": [],
		"Pos": "",
		"Err": "directory ../bar outside available modules"
	}
}
$ echo $?
0

@matloob can you confirm this is now working as intended?

[matloob]

Yeah, it's now working as intended. Closing.
