I think you somehow have an outdated Seq.java in play. Seq.java in gomobile master doesn't have that code anymore.

[dcu]

how can this happen? I'm able to reproduce in 2 different computers

[eliasnaur]

I'm not sure, and I can't reproduce the error locally either. Do you have multiple copies of Seq.java in your GOPATH?

[dcu]

someone vendored gomobile and that was causing the issue, thanks ! the issue is fixed now.

What version of Go are you using? You need at least go 1.7 to use go mobile. Den man. 3. jul. 2017 18.34 skrev longtq6195-seta-international < notifications@github.com>:
