This document discusses continuous delivery in an open source project. It begins with an introduction of the speaker and then discusses various tools used in the continuous delivery process like Travis CI for continuous integration. It outlines the build pipeline for the project including deploying to Bintray and updating GitHub pages. It also covers code quality tools like Codecov and promoting the project on the internet through blogs, conferences and other forums.

23. Continuous Integration

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

25. Continuous Integration
https://travis-ci.org
● Free for Open Source Projects
● Easy setup with GitHub
● Container based 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

26. How to set up Travis-CI
.travis.yml
language: java
script: mvn clean install
jdk:
- oraclejdk8
● Sign in to 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

27. Default Travis-CI java build
.travis.yml
language: java
jdk:
- oraclejdk8
.travis.yml
language: java
install: mvn install -DskipTests=true -Dmaven.javadoc.skip=true -B -V
script: mvn test -B
jdk:
- oraclejdk8
Default Travis-CI maven build seps:
● install
● script

28. Default Travis-CI java build
.travis.yml
language: java
jdk:
- oraclejdk8
.travis.yml
language: java
install: mvn install -DskipTests=true -Dmaven.javadoc.skip=true -B -V
script: mvn test -B
jdk:

Default Travis-CI maven build seps:
● install
● script

29. Default Travis-CI java build
.travis.yml

30. 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

33. Current IceBoar Build in nutshell
#!/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

34. Continuous Delivery

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

36. Release artifact to Maven Central is not so easy
Complicated Requirements:
● Supply Javadoc and Sources
● Sign Files with GPG/PGP
● Sufficient Metadata (pom file)
● Correct Coordinates (groupId, artifactId, version)
● Project Name, Description and URL
● License Information
● Developer Information
● SCM Information

37. 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

38. Bintray general repository settings

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

41. Code Quality

42. Code Quality with codecov.io
● Sign in to 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

43. Codecov see Code Coverage

44. Codecov Extension (for Chrome) - see coverage on GitHub
