Shipkit demo

This is a demo project that showcases release automation with Shipkit plugins. Use it as a reference to automate your project!

Overview

This project represents a development model where every change on the main development branch will produce a new release via the CI system. The release is a Maven publication (jars, poms) that get uploaded to a free public repository (Maven Central) via a free CI system (GitHub Actions). We chose Maven Central and GitHub Actions as examples - you can use any system of your choice (for example: JFrog Artifactory + Travis CI). The Gradle plugins we chose for this use case represent the minimum set of Gradle plugins to conveniently automate the releases.

• the Maven publication (jars, poms) is configured using Gradle's built-in maven-publish plugin.
• the publication to a public repository (Maven Central) is configured using gradle-nexus/publish-plugin plugin. Published versions and artifacts can be viewed in Maven Central. If you want to publish to a different repository than Maven Central, you would use a different plugin for that. For example, if you want to publish to JFrog Artifactory, you can use com.jfrog.artifactory plugin.
• the next version for the release is deducted automatically by shipkit-auto-version plugin. This plugin is minimalistic, written for sole purpose of automated deduction of version before the release.
• the GitHub release is performed via GH REST API by shipkit-auto-version plugin. This plugin is minimalistic, written for sole purpose of generating changelog (release notes) and performing a GH release. The releases and changelog can be viewed on GH releases page.

Implementation reference

• Java publication (javadoc/sources jar, pom customization, signing): gradle/java-publication.gradle. Note that PGP_KEY and PGP_PWD environment variables are required for successful publications.
• Release automation (deducting version, generating changelog, creating GitHub release via GH REST API, Sonatype/Maven Central settings): gradle/release.gradle. Note that GITHUB_TOKEN env variable is required to perform GitHub release. SONATYPE_USER and SONATYPE_PWD are required for publications to Sonatype Nexus (Maven Central).
• CI/CD configuration: .github/workflows/ci.yml. Note that you can use any CI system.
