I hit this issue while trying to build this project: ipfs-shipyard/gomobile-ipfs (from the packages folder)

go version 1.18.2 was being used and there was one go module in dependency chain requiring go 1.17:

# github.com/lucas-clemente/quic-go/internal/qtls
../pkg/mod/github.com/lucas-clemente/quic-go@v0.24.0/internal/qtls/go118.go:6:13: cannot use "quic-go doesn't build on Go 1.18 yet." (untyped string constant) as int value in variable declaration

exit status 1
make: *** [Makefile:112: /home/wesley/devel/gomobile-ipfs/packages/build/android/intermediates/core/core.aar] Error 1

I've installed go 1.17.11 and it fixed the issue for me.

@WesleyBatista Your issue is not the same. github.com/lucas-clemente/quic-go does not support Go 1.18 until 0.25.0. See https://github.com/lucas-clemente/quic-go/releases/tag/v0.25.0

@ZekeLu thanks for your comment!

I understand my issue is not the same, but I believe the root cause lies in the fact that there was an unexpected outcome during the build (a package/module failed to build) that ultimately caused the exit status 2 we see at the end, which is pretty much the same as op.

In my case the problem was the go version, but exit code 2 could be anything that fails and causes a misuse of shell built-ins, as described here: https://tldp.org/LDP/abs/html/exitcodes.html

does anybody have any idea how to fix the problem that @unifyproxy mentioned?

i tried to generate .aar file but i get the same error
go version => 1.20
ndk version => 21.3.6528147 (tried to use the latest but i get an error so i switch to the earlier one and then fix the problem with ndk version)
but i get the same error when trying to bind go code (gomobile bind -v -androidapi 19 -ldflags='-s -w' ./)
repo =>V2fly
error =>
