Continuous delivery is a software engineering approach where code changes are automatically built, tested, and prepared for a release to production. The presentation discusses setting up a continuous delivery pipeline for an open source project including continuous integration with Travis CI, deploying to Bintray, tracking code quality with Codecov, and promoting the project online. Alternatives to Travis CI, Codecov and other tools are also presented.

22. Continuous Integration

23. Continuous Integration
https://travis-ci.org
● Free for Open Source Projects
● Easy setup with GitHub
● Container base architecture (Doker)
● Stateless

24. Continuous Integration
https://travis-ci.org
● Free for Open Source Projects
● Easy setup with GitHub
● Container base architecture (Doker)
● Stateless
● Multi language support (ANDROID, C, C#, C++, CLOJURE,
CRYSTAL, D, DART, ERLANG, ELIXIR, F#, GO, GROOVY,
HASKELL, HAXE, JAVA, JAVASCRIPT (WITH NODE.JS), JULIA,
OBJECTIVE-C, PERL, PERL6, PHP, PYTHON, R, RUBY, RUST,
SCALA, SMALLTALK, VISUAL BASIC)
● For Java: Oracle JDK 7 (default), Oracle JDK 8, OpenJDK 6,
OpenJDK 7, Gradle 2.0, Maven 3.2 and Ant 1.8
● Notifications via: Slack, HipChat, Emails and more

25. How to setup Travis-CI
.travis.yml
language: java
script: mvn clean install
jdk:
- oraclejdk8
● Sign travis-ci.org using GitHub account
● Choose project (you need to have admin rights to this project)
● Add .travis.yml to your root project folder

26. Store sensitive data (passwords) on travis-ci
<settings ...>
<servers>
<server>
<id>bintray-stachnim-IceBoar</id>
<username>${env.CI_DEPLOY_USERNAME}</username>
<password>${env.CI_DEPLOY_PASSWORD}</password>
</server>
settings.xml

27. Store sensitive data (passwords) on travis-ci

28. Store sensitive data (passwords) on travis-ci

29. Current IceBoar Build
#!/bin/bash
set -ev
if [ "${TRAVIS_PULL_REQUEST}" = "false" ];
then
cd ice-boar && mvn clean deploy --settings …
else
cd ice-boar && mvn clean install && ...
fi
build-travis.sh
language: java
script: ./build-travis.sh
jdk:
- oraclejdk8
.travis.yml

30. Continuous Delivery

31. Release artifact to Maven Central is not so easy
● Complicated Requirements
● Hard to sign in / create account (need to find link and create an issue)
● Manual verification of uploaded artifact

32. Release artifact to bintray
● Sign in with GitHub
● Add new package to maven repository, configure it
● Deploy to bintray (from Travis-CI)
● You don’t need to sign your artifact

33. Bintray general repository settings

34. Bintray deploy to Maven Central
● You can’t store user token password :-(
● This will be manual step :-(

36. Code Quality

37. Code Quality with codecov.io
● Sign in codecov.io with GitHub
● Configure jacoco-maven-plugin
● Add to .travis.yml:
language: java
script: ./build-travis.sh
jdk:
- oraclejdk8
before_install:
- pip install --user codecov
after_success:
- codecov
.travis.yml

38. Codecov see Code Coverage

39. Codecov Extension (for Chrome) - see coverage on GitHub
https://chrome.google.com/webstore/detail/codecov-extension/

40. Codecov suggestions

41. Nice badges

42. Nice badges

43. Promotion in the
Internet

44. What is important for users?
● Nice demo page with example usage: roche.github.io/IceBoar/

45. What is important for users?
● Easy setup for contributors

46. What is important for promotion?
● Stack Overflow: stackoverflow.com/search?q=ice+boar

47. How to promote in the Internet?
