Intro

This article documents the process for integration of the android client library release process to the CI for automation i.e CI/CD on Github. On needs admin rights on the repository to set up the credentials for the Github Actions CI pipeline.

This set up supports tagging releases on Github as pre-releases if they include alpha or beta keyword in the tag e.g. v2.3.5-alpha

Credentials configuration

Your applications build configuration should have the Nexus credentials configured in-order to be authorised to upload an artifact in the OpenSRP organization/group on sonatype.

...

For steps to manually publish the artefacts see How to upload and use maven jar artifacts

Github Actions CI

You can create a new Github action workflow file and name it release.yml with the following sample configuration used for building, signing and publishing the FHIR Core Quest application as a Github release.

NOTE: Remember to update the content with the module names corresponding to your project.

# This workflow will build a Java project with Gradle
# For more information see: https://help.github.com/actions/language-and-framework-guides/building-and-testing-java-with-gradle

Publishing via TAG

As part of integrating Continuous Delivery(CD) into the development lifecycle, CI has been set up to trigger artefact generation. The configuration requires the tag to have a prefix in the glob pattern formats:

v[0-9]+.[0-9]+.[0-9]+-SNAPSHOT

...

Also please see Semantic versioning

Accessing your releases

Once the above command is executed and the tag is pushed, Github CI triggers an action to build the artefact and upload it to Sonatype.
