Gradle Changelog Automation Plugin

Inspired by GitLab: https://about.gitlab.com/2018/07/03/solving-gitlabs-changelog-conflict-crisis/

What does this plugin do

This plugin is able to generate CHANGELOG.md from YAML files. One YAML file represents one unreleased changelog entry. For example, a new added feature's entry would look like this:

title: My new feature
reference: GH-1
author: John Doe
type: added

Then the plugin can process the unreleased YAML entries and combine them into CHANGELOG.md. The changelog is based on Keep a Changelog.

As an example, see this project's changelog which is automatically generated by this plugin: CHANGELOG.md.

Getting started

How to apply the plugin

Using the plugins DSL:

plugins {
    id 'org.zkovari.changelog' version '0.4.0'
}

Or using legacy plugin application:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.zkovari.changelog:changelog-automation-gradle-plugin:0.4.0'
    }
}

apply plugin: 'org.zkovari.changelog'

How to generate YAML entries

The plugin contains a generator script that you can fetch with the fetchChangelogScript task:

gradle fetchChangelogScript
# result: scripts/changelog.sh

# add permission
chmod +x scripts/changelog.sh

To generate a new unreleased changelog entry (YAML), run changelog.sh:

./scripts/changelog.sh --type added "My new feature"

As a result, a new changelog entry is generated under changelogs/unreleased, in this case the following one:

title: My new feature
reference:
author:
type: added

See changelog.sh --help or the detailed documentation for further information.

How to process unreleased changelog entries

If you already have unreleased YAML entries under changelogs/unreleased, you can combine them into your CHANGELOG.md with the task processChangelogEntries:

gradle processChangelogEntries

As a result, your CHANGELOG.md is updated with a new release entry. As an exmaple, see this project's changelog which is automatically generated by this plugin: CHANGELOG.md.

The task processChangelogEntries also removes your unreleased entries from changelogs/unreleased.
