How to set up Travis CI with multiple languages

Question

My project uses both nodejs and java

I tried starting off with a node_js build then installing java (since this is an npm module)

but the scripts to install java failed, plus I don't think there's a need to install it when there is a build with java that already exists.

should I start off with a java build then install node?

I'm trying this

language: java   - oraclejdk8 language: node_js node_js:   - "0.10" 

which ignores the first 2 lines it seems and builds a node_js build which has java 7 and my project uses java 8

I tried this answer for python

using

language: node_js node_js:   - "0.10" java: oraclejdk8 

but that didn't work

How can I add java 8?

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.

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.
