What version of Go are you using (go version)?

go version go1.13 windows/amd64

Does this issue reproduce with the latest release?

What operating system and processor architecture are you using (go env)?

What did you do?

  • go get github.com/fatedier/frp
  • vi {GOPATH}/github.com/fatedier/frp/cmd/frpc/sub/export.go
package sub

import (
	"time"
	"math/rand"

	_ "github.com/fatedier/frp/assets/frpc/statik"
	
	"github.com/fatedier/golib/crypto"
)
// I want to export this function only
func Start(filePath string) {
	crypto.DefaultSalt = "frp"
	rand.Seed(time.Now().UnixNano())

	runClient(filePath)
}

open terminal
gomobile bind -target android github.com/fatedier/frp/cmd/frpc/sub

What did you expect to see?

gomobile create a .aar and .jar file

What did you see instead?

Any update here? gomobile bind -mod vendor says "flag provided but not defined: -mod". Without the flag, it always downloads packages ignoring vendor/ dir just like with a regular build.

This is on go1.14.

Some further digging, starting from scratch:

From: https://pkg.go.dev/golang.org/x/mobile/cmd/gomobile

$ go install golang.org/x/mobile/cmd/gomobile@latest
$ export PATH=$PATH:/home/user/go/bin
$ gomobile init
$ gomobile version

gomobile version unknown: cannot test gomobile binary: exit status 1, no required module provides package
golang.org/x/mobile/cmd/gomobile: go.mod file not found in current directory or any parent directory; 
see 'go help modules'

Ok, so in a module:

$ mkdir test ; cd test ; go mod init test.com
go: creating new go.mod: module test.com

And: git init ; echo "test" > readme.md ; git add readme.md ; git commit -m "Initial" 

$ go mobile version

gomobile version unknown: cannot test gomobile binary: exit status 1, no required module provides package
golang.org/x/mobile/cmd/gomobile; to add it:

    go get golang.org/x/mobile/cmd/gomobile

Run go get:

$ go get golang.org/x/mobile/cmd/gomobile                                               
go: added golang.org/x/mobile v0.0.0-20220722155234-aaac322e2105      
go: added golang.org/x/mod v0.4.2                                     
go: added golang.org/x/sys v0.0.0-20210809222454-d867a43fc93e         
go: added golang.org/x/tools v0.1.8-0.20211022200916-316ba0b74098     
go: added golang.org/x/xerrors v0.0.0-20200804184101-5ec99f83aff1     

$ go mod tidy
go: warning: "all" matched no packages

$ gomobile version

gomobile version unknown: cannot test gomobile binary: exit status 1, no required module provides package
golang.org/x/mobile/cmd/gomobile; to add it:

        go get golang.org/x/mobile/cmd/gomobile

Ok, try example:

Download https://cs.opensource.google/go/x/mobile/+/aaac322e:example/basic/main.go

$ go mod tidy
go: downloading golang.org/x/exp v0.0.0-20190731235908-ec7cb31e5a56  
go: downloading golang.org/x/image v0.0.0-20190802002840-cff245a6509b

$ go mod vendor
$ gomobile version

gomobile version unknown: cannot test gomobile binary: exit status 1, cannot find package "." in:
        /home/user/test/vendor/golang.org/x/mobile/cmd/gomobile

Ok, apparently golang.org/x/mobile/cmd/gomobile is never added to go.mod since not being a dependency.
Force dependency by adding package to main.go:

	_ "golang.org/x/mobile/cmd/gomobile"

Try again:

$ go mod tidy
$ go mod vendor
$ gomobile version

gomobile version unknown: binary is out of date, re-install it

Here is when the error is triggered in go mobile source:
https://github.com/golang/mobile/blob/8578da9835fd365e78a6e63048c103b27a53a82c/cmd/gomobile/version.go#L46

Apparently go list -f {{.Stale}} golang.org/x/mobile/cmd/gomobile should return false, but it returns true in our test module:

$ go list -f {{.Stale}} golang.org/x/mobile/cmd/gomobile
true

If we use StaleReason:

$ go list -f {{.StaleReason}} golang.org/x/mobile/cmd/gomobile

We get:

stale dependency: golang.org/x/mobile/internal/sdkpath

On other test repo we get the same reason, just a different dependency path (e.g. stale dependency: cgo)

My current knowledge of golang doesn't go as far as to know how to investigate this further. Hope someone else can pick this up.

go version go1.18.3 linux/amd64
