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:
- yourname@gmail.com
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.
