gomobile: command not found

Question

I have some codes written in golang which is compiled to aar and used as library in android app via gomobile. On my windows machine everything works well as I have everything configured correctly. Now I am trying to automate the build process using GitHub action and having trouble setting it up using ubuntu. The problems I am having I believe they are associated with setting PATH which on ubuntu.

Here is my workflow for building my project

on:
  push:
    branches:
      - main
      - actions

name: "Build & Release"
jobs:
  generate:
    name: Generate codes
    runs-on: ubuntu-latest
    permissions:
      contents: write
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-go@v3
        with:
          go-version: '1.18'

      - uses: actions/setup-java@v2
        with:
          distribution: 'zulu'
          java-version: '11'

      - name: Installing go server dependencies
        working-directory: server
        run: |
          go install

      - name: setup-android-tools
        uses: maxim-lobanov/setup-android-tools@v1
        with:
          packages: ndk;19.2.5345600

      - name: Build aar
        working-directory: server
        run: |
          go get -d golang.org/x/mobile/cmd/gomobile
          gomobile init
          gomobile bind -v -o ../client/app/libs/server.aar -target=android ./lib

      - name: Push aar to release
        uses: ncipollo/release-action@v1
        with:
          artifacts: "${{ matrix.dir }}/client/app/libs/*aar"
          tag: v1.0.${{ github.run_number }}
          token: ${{ secrets.GITHUB_TOKEN }}

The following is Go ENV as printed by setup-go

  GO111MODULE=""
  GOARCH="amd64"
  GOBIN=""
  GOCACHE="/home/runner/.cache/go-build"
  GOENV="/home/runner/.config/go/env"

And the following is the actual error I get when executing gomobile

go: downloading golang.org/x/mobile v0.0.0-20220518205345-8578da9835fd go: downloading golang.org/x/mod v0.4.2 go: downloading golang.org/x/tools v0.1.8-0.20211022200916-316ba0b74098 go: downloading golang.org/x/xerrors v0.0.0-20200804184101-5ec99f83aff1 go: upgraded golang.org/x/mobile v0.0.0-20220504144722-50dca8fc073d => v0.0.0-20220518205345-8578da9835fd /home/runner/work/_temp/8ee34a1b-b28d-4781-9668-9aa41d593cce.sh: line 2: gomobile: command not found

How can I successifully build aar using github action. Any help will be appreciated.

Here is GitHub repository for this project.

Answer 1

I would recommend using this step to configure gomobile once you setup Go on your runner:

- name: Install Gomobile
  run: |
      go install golang.org/x/mobile/cmd/gomobile@latest
      go install golang.org/x/mobile/cmd/gobind@latest
      go get golang.org/x/mobile/cmd/gobind
      go get golang.org/x/mobile/cmd/gomobile
      gomobile init
   env:
      GOPROXY: https://proxy.golang.org,direct
      GO111MODULE: "on"

If it doesn't work out, I would be happy to look into this further and raise a fix on your GitHub repository itself :)

Answer 2

download & install go from here ( https://go.dev/dl/ ) open cmd type go install golang.org/x/mobile/cmd/gomobile@latest after download gomobile init work.
