How to set up Travis CI with multiple languages

Solution 1:

It seems to be possible now to run several languages in one .travis.yml file using the jobs:include feature. As an example, my Github repo is arranged as follows:

project/ - top-level github directory
project/backend - Python backend
project/backend/tests - Python tests
project/android/AppName - Android app
project/ios/AppName - iOS app

Here is the .travis.yml, which runs tests in Python, Java, and Objective-C:

jobs:
  include:
    - language: python
      python: 2.7
      before_script:
        - cd backend/tests
      script:
        - python -m unittest discover

    - language: android
      dist: trusty
      jdk: oraclejdk8
      android:
        components:
          - tools
          - android-25
          - build-tools-25.0.3
      before_script:
        - cd android/AppName
      script:
        - ./gradlew build connectedCheck

    - language: objective-c
      os: osx
      osx_image: xcode8.3
      before_script:
        - cd ios/AppName
      script:
        - xcodebuild -workspace AppName.xcworkspace -scheme AppName
          -destination 'platform=iOS Simulator,name=iPhone 7,OS=10.3' build test

notifications:
  email:
    - [email protected]

It seems you can build as many different configurations as you like using this feature, by treating each entry in the matrix as a top level config. Of course, if you have any parameters you want to set that apply to all languages, you can do that at the top level, as I do here with the notifications:email section.

When it is all set up, then on each build, you get something like this. Boom.

Solution 2:

On a Travis Java build environment, you can use nvm to manage Node.js runtimes:

.travis.yml

language: java

jdk:
  - oraclejdk8

env:
  - NODE_VERSION="0.12"

before_install:
  - nvm install $NODE_VERSION

If your Node version is very recent, you might have to update nvm too.

To update nvm, write this in your .travis.yml:

before_install:
  - wget https://raw.githubusercontent.com/creationix/nvm/v0.31.0/nvm.sh -O ~/.nvm/nvm.sh
  - source ~/.nvm/nvm.sh
  - nvm install 5 # for Node v5
  - node --version

The above example shows how to first update to nvm v0.31, to then obtain Node v5.
