What did you do?

Prepare this project

module mobiletest

package foo

import (
        _ "golang.org/x/mobile/app"

func Dummy() {}

and run

gomobile bind .

The gomoible version is fbe1c053b6a9fb82bd32271219fa206af328fa80
The go.mod is created by go mod tidy and modified to depend on golang.org/x/exp

What did you expect to see?

No error

Unfortunately, it seems impossible to resolve this go.mod, even though the Go version is specified.

module gobind

go 1.20

replace mobiletest => /Users/hajimehoshi/test/mobiletest

I've confirmed that the 'regular' go.mod (requiring golang.org/x/exp/shiny, not golang.org/x/exp)

module mobiletest

go 1.20

require golang.org/x/mobile v0.0.0-20230905140555-fbe1c053b6a9

require (
	golang.org/x/exp/shiny v0.0.0-20230817173708-d852ddb80c63 // indirect
	golang.org/x/image v0.11.0 // indirect
	golang.org/x/sys v0.11.0 // indirect
)

also fails to be compiled with the same error. Instead, this can now be compiled with my fix https://go-review.googlesource.com/c/mobile/+/525695. So my fix cannot fix the original issue, but can fix the above issue.
