Distributing to a public or private Maven repository

Slides from my talk at Droidcon Paris 2015
video: http://droidcon.fr/schedule/#session-410

In order to remain cost effective reusing code is one of the most essentials skills of a modern Android developer. Using open source libraries is one thing, but what if there isn't a library available that suits your need? How would you go about to develop and distribute this library yourself?

This talk aims at providing a complete solution for library distribution, either within your own organisation or with the entire open source community. You will learn how to setup your own private Maven repository, configure an account for Maven Central or JCenter and that even BitBucket/Github can be used as a Maven repository! Fully functional Gradle scripts will be provided for each alternative, taking important aspects like security and nested dependencies into account.

After this talk, there will be no more excuse to ramp up your game and start reusing your own code!

1. DISTRIBUTE TO A PRIVATE OR PUBLIC MAVEN REPOSITORY @MOLSJEROEN
2. BEFORE SOFTWARE CAN BE REUSABLE IT FIRST HAS TO BE USABLE. Ralph Johnson
3. MAVEN FUNDAMENTALS
4. @MOLSJEROEN WHAT IS MAVEN
5. @MOLSJEROEN HOW MAVEN STORES ARTIFACTS ▸ Artifacts: artifact.aar, javadoc.jar, sources.jar,… ▸ Project Object Model ▸ GroupId ▸ ArtifactId ▸ Version

16. THERE IS AN EASY WAY AND A HARD WAY. THE HARD PART IS FINDING THE EASY WAY. Dr. Lloyd
17. PUBLIC DISTRIBUTION

19. @MOLSJEROEN NEXUS ▸ Cumbersome to set up ▸ Register and log a Jira issue ▸ Configure GnuGP to sign artifacts ▸ Upload to staging environment via Gradle ▸ Manually release the artifacts ▸ Wait for sync to Maven Central
