Java builds on Travis CI .org

I’d seen the name Travis a number of times in relation to Continous Integration, but never having any non-work repositories I’d never paid any attention to anything other than Jenkins.

But since starting on more private projects I did come to miss not having a  ‘it works on my machine’ check. I didn’t really have an appetite to setup Jenkins locally, although it might not be much hassle with Docker and compose, it just wasn’t something I wanted to spend time on.

The org site is specifically set up to ease integration with your own Github repositories. Once you’ve signed in with the SSO/SAML magic you’re given a list of your private repos and simple tick boxes for which you want to enable.

From there is a tiny domain-specific language file you need to insert into the root of your repo. I’ve included the simplest Java one I could get away with as an example below.

file: .travis.yml

language: java
- oraclejdk8
sudo: false
script: mvn clean verify

The build will then trigger whenever you push to the repo. Each build produces a summary plus the raw build process output.
